Hello everybody, here I am again with my questions. Looking at photos of PT 728 and PT 695 I noticed that rudder shafts look similar on both boats. So I have a question is it original design of shafts on photos?

Welcome back,
I was thinking of you when I saw this set. Have you seen it?

Holy moly!

That Griffon Models photo-etch set for the Italeri Vosper is certainly extensive and all-inclusive.

Really nice set of parts. But not my scale and not my type of Vosper unfortunately.

Hello Igor,
Lets see if this helps,per Al Ross and John Lamberts Allied Costal Forces of WW11 Book the Annapolis drawings for PT661-730 Licence built Vospers, they were fitted with three rudder shafts as per the photos of "PT728" you posted, however the cavitation plate was of a slightly different design it extended all the way across the stern with a 45 degree angle starting from the hull towards the centre line of the hull and meeting the end of the plate with a fair curve not a point.
The one that the 728 is fitted with at the moment may be a replacement due to age.
Out of just pure silliness the boat that was used as PT73 in McHale's Navy was also one of the same batch and some of the views that can be seen during the show allow many interesting areas to be seen of the boat.
I have watched the show and one of the areas that did draw my attention was the stern with the form of rudder shafts as seen on the PT728 as I did find it differant to the Elco boats.
By the way which Vosper are you building. This late version or one of the earlier boats.

Hello David,

PT 728 photo shows original cavitation plate of late design Vosper boat. There is muffler guard rail on Al Ross drawing going at 45 degrees from edge of transom. Cavitation plate has the same shape as on photo and it can be seen on drawing.
I am building TK234 (ex PT405). Drawings of PT 723 in the book you mentioned shows this type of Vosper boat.
Interesting details on PT 728 photo are holes for exhaust tubes in cavitation plate. Drawings don't give clear view of this place.
Here is my progress with wooden project:


I've tried to watch McHale's sitcom, but couldn't find anything valuable there. So if you could advise what part to watch I'll appreciate it very much.

Igor.

Hi Igor,
Yes you are correct that is a muffler guard.

McHales Navy episode /movie of when they take /borrow a race horse to New Caledonia (were do you find a race horse in the South Pacific?)

The frame looks great having made a couple of 1/24 scale scratch built models I understand what it takes to just get that far.

By the way I note the ruler in front is that a 60 cm one and if so what scale is the model?

After a little research I think I now know which design you are following this version had twin 50 cal. turrets and Higgens torpedo tubes, I don't know if this version had the exhaust you are asking about.

OK now for a little odd ball info there is a picture in Ospreys Publishing, British Motor Torpedo Boat 1939-45 of MTB 375(page 14). As seen see is in standard 70' Vosper British finish ie. sloping forward end to the Torpedo tubes, single 50 cal. turret fitted with water cooled 50s and what looks to be a single 20mm up front. The write up for the picture says that various boats from the same batch were sent to the Russian Navy.

And on to the odd ball bit Revell has a 1/72 model kit that has the 375 as its basis? for the kit however instead of the kit being of a standard British version this kit has all the changes for a Vosper that was delivered to the Russian Navy. As Revell do a fairly good job of getting most! things right on their kits, I find this rather interesting.

However another way of thinking about how they came to produce this model is that they must have had a drawing or two to follow, might not hurt to email them and see if they may be able to assist you with a copy or two. It is fitted with the exhaust system on the model out of interest.

Hi David,
About scale. This one is 1/24 and ruler is 50 sm. 1/4 of boat is not complete - need to prepare shaft tubes. They are not ready at the moment.
Revell 1/72 model is awful. Its hull, rudders, bridge and transom are totally incorrect. Lots of mistakes so it would take very much time to explain. I posted here links to photos of two of that 8 boats built by Annapolis for Great Britain that went to SU later. They got Higgins tubes as you call them and twin browning water cooled machine guns mounted instead of British Vickers MGs.
Here is a link to that thread:

A skilled modeler could definitely modify the Revell 1/72nd scale Vosper kit to closely approximate the "McHale's Navy" TV series/movie "PT 73" -- if one wanted to.

Torpedo tubes from Revell's "PT 109" (or any of its other incarnations) 80' Elco kit should be used for the "McHale's" PT 73, as the tubes on the TV boat had those types as the two (forward) tubes, not the ones that come in the Vosper kit.

There's a good (b&w) screen capture of the (port) forward half of the boat at speed, taken from the opening titles of the TV series, floating around on the internet, and there are great (color) aerial shots of the boat at speed at sea under the titles of the movie.

Hi Igor,

Ok after a fruitless night of trying to find Russian MTBs on the net I was wondering what your thinking is for the TK-234 being fitted with the stern muffler system and it you have any pictures of her or any of the same batch of boats with that system fitted or was that system only fitted to the later boats.

You may have a starboard forward quarter photo of the 234, she is with the nest of boats with her next to a sister boat in front of the rest of the boats the number 34 can be seen on the mg. turret, the other boat being 229 I think in your first batch of photos you posted?

Out of interest looking at the drawings it appears that there may not have been to much room between the cavitation plate and the top of the rudders and even with the holes in the plate the end of the muffler pipe would not have gone to far beyond it, however the drawings that are around seem to show that the pipe leading from the muffler stopped just above the plate.

Per your question to Al Ross do you intend to plank the hull of your model as per the original?

Going back to the photo of what I think is the 234 she seems to be a fairly clean boat not to many odd add ons which make for a nice model?
