Yes Dave, the base line is parallel to the waterline and about 5.25" below the lowest part of the hull. Elco used it as a construction reference on drawings like the frame offsets and heights of the day room and chart house.
The tops of the turrets were square to the base cylinder so neither design was parallel to the deck.
One interesting construction detail I found was that the turret base cylinders were constructed from three layers of 9/64" (0.141") birch plywood glued on a mold. Mighty thin at about 3/8", common knowledge had them at 3/4".
Some other turret details from Elco PT 103-196 and 314-367 drawings:
Forward turret center location:
51" starboard of center line.
446.75" aft of foremost point (8 1/4" forward of frame 33).
Aft turret center location:
34" port of boat center line.
672" aft of foremost point (22" aft of frame 47).
Turret height:
39 5/8" from top of coaming to top of machine gun mounting ring.
Measurement taken at inside of turret at forward end.
Top of coaming is about 5 11/16" above deck.
Machine gun mounting ring, sits on top of base:
51 1/2" O.D. x 42 3/4" I.D. x 1/2" thick birch plywood.
Machine gun mounting ring outer skirt:
50" I.D., 3/4" x 2 1/8" steam bent oak.
Under the machine gun mounting ring, between the base cylinder and the outer skirt, were twelve 3" x 3" square aluminum tube support brackets. These were 3 1/2" height at the base cylinder with the bottoms tapered to 2" height at the outer skirt. Between the brackets were 3/4" x 1 3/8" oak segments mounted to the base cylinder with tops flush with the bracket tops.
Inside the turrets were two floors, a watertight 5/8" plywood bottom floor which rested on the coaming at the forward end, and a top floor / depress firing step which had a hole cut in the center to form a 10" wide ring. The top of the upper floor was 9" above the top of the bottom floor.
I hope this helps, keep up the good work!

A simple illustration to demonstrate what Jeff has detailed.

Thanks for the insider info. With the ammount of information available on this site one could build a very, very, detailed model. It's tempting. And this raises the question that if all this info is availble, why are the kits always so bad? Some things need to be altered because of molding limitations, but still.
I saw on another thread here the detailed engine room on a 1:72 model. Amazing. And with 3D computer modeling and cheap laser cutters and 3D printers a person could replicate almost the entire boat down to correct planking and frames.
When I was building the 196 boat I asked a bunch of questions on another site. Most of them were about general construction, like how the foot steps, hand rails and masts were built. I didn't find this site until later. I am still looking for a subject boat for my other Lindy PT. An early war example, with tubes forward and depth charges aft.

Hi there Boater Dave.
Here are some of my thoughts as to why I feel that the level of detail is what it is on some maufacturers kits.
Cost to the purchaser.
The 1/35 scale Italeri PT-596 kit is about $150.00 now in the average hobby shop in the area here where I live. If this kit was much more detailed it would be considerably more expensive and thus less affordable to many more modellers..
What the model builder wants.
Many model builders are quite content to turn out a model that represents the subject. They are not looking for an exact minature replica of a particular boat as it appeared at a particualar period of time. Many are even content and happy to build a model that has different features from differing time periods mixed together.
What the model is designed for.
Many modellers greatly enjoy building the 1/32 scale Lindberg PT-109 kit because it is simple to assemble, has few parts that can be knocked off in transport and in use as radio control boat model.
I'm positive that if Italeri were to offer a simpler version of their 80' foot Elco boat such as the PT-103 Class, at a lower price that reflects not having the 40 mm Bofor gun and other additional arnaments, that they would sell many of them to both static boat modellers and those who want to get into radio control inexpensively. A PT-103 Class kit from Italeri that retailed for $100.00 would be fantastic as that is about what the 1/32 scale Lindberg PT kit sells for here.
The age the kit is intended for.
I really think that the Lindberg kit was designed for the young and/or inexperienced modeller. It was also designed to be motorised and/or radio controlled. As such many details were left off it mad many of the parts were designed for rough handling by the modeller.
If the Italeri kit is built as a radio controlled model there are an awful lot of very delicate parts that can be knocked off and possibly lost just launching and retrieving the model from whatever body of water one uses.
You are planning on possibly building another Lindberg PT boat model with just the forward torpedo tubes and depth charges where the aft torpedo tubes were? I built my first Lindberg PT boat model in that configuration. I built the forward torpedo tube racks so that they can be positioned outboard as well as in the inboard stowed position. There are image of it somewhere on this forum in a message I posted about it. I'm not sure where that message is. The images are in my Peter Tare Builder photo album over on the images ection of this forum.
One last thing to consider is the time frame a model manufacturer has between deciding to create a kit and releasing it. I think that Lindberg rushed their research into their 1/32 kit and hastened to get it out to capitalize on the release of the theatrical film PT-109 and thus did not do as much research as they might have wanted to. They also seemed to have cut corners to speed developement by using the hull and helm from their Chris Craft model. I say that because images I have seen of the 1/20 scale Lindberg Chris Craft (Sport Fisherman cabin cruiser) appears to use the identical hull that their PT -109 kit does and the helm in the latter kit looks like something you'd find on a civilian vessel and the large size of that helm is much more in keeping with a scale size of 1/20 than it is of 1/32 scale.
So there you have some of my thoughts as to why some model kits are not as accurate as some of the purist would like.
Cheers from Peter

Hi there Boater Dave.
Here is the link to the thread that has images of my PT-105 type boat under refurbishing.
http://www.ptboats.org/cgi-local/sitenetbbs/netboardr.cgi?fid=102&cid=101&tid=1797&sc=20&pg=1&x=0
Not much work has been done since those images were taken. I do have the depth charges though they were not on the model when I took mot of the images. The depth chargers were made from 1/35 scale Tamiya fuel drums with the inner section of 1/32 Wlaker Duster roadwheels used for the ends.
Cheers from Peter

Nice work, just getting started in PTs and looking around for what can be done with some of these kits.
Cheers!
