Luis, nice E mailing you about the 1:72 Navy Officers in Kaki Uniforms and Visor caps. I am so looking forward to seeing these and purchasing what we need for the MTBSTC diorama.

Hi Jeff.

Yes, this is what I say, in this drawing you can watch some features that can't be seen in the real pics (sadly not too much photos available) or are different.

Anyway, I can do the model to exactly match this drawing. Tell me about your scale.

Best regards

Luis

I'm going to email Luis and request he make (2) running lights and (3) air scoops in 1/72nd scale for the charthouse of the Revell 1/72nd PT 109/PT 117/PT 167/PT 191 kit(s).

Luis, are you listening?

I think the arrows are pointing to the actuating levers Luis. You're right, images of mufflers are hard to find. Here's some I had of varying quality, hope they help:

PT 117:



PT 562, with the stepped hull they were experimenting with:



Unknown Elco 80, note the short stout outlet:



This one is interesting, it shows 2 types of mufflers on 1 boat:



An Elco 80 in the UK:

Hi Jeff:

Great pics!

These let me clear that the drawing shows a real muffler.

Anyway, third pic you post shows the cover staggered from the tube, just like in the pics I've sent.

Then I think both types exist.

Best regards

Luis

Bridge Carney did a lot of research on the mufflers when he was building PT157 model and writing his book "The PT-157: A Scale Model Builder's Notebook", Maybe he can contribute something.

The PT silencing muffler system was a very unique and essential feature given the nature of the 'Close Quarters' fight. It was how PTs evaded detection at such close ranges. Without it the growl of those Packard engines would have given their position away...and with dire consequences.

It was almost impossible task to recreate mufflers, linkages and salt water (piping) connectors for modeling purposes until the ELCO blueprints arrived on scene.

The silencing muffler system configuration seem to change throughout production for reasons likely lost in history (such as possibly making them better, or supplier variation or make them easier to maintain..I don't really know) so you have to research which specific PT boat number you interested in. Even in the photos posted earlier in this post it is not easy to see some of the details.

Check on which [Washichek collection] ELCO blueprints that would apply by looking at the title block on the right side of drawings (note: some drawings are in multiple sections). They typically list which PTs that drawing applies.

HELPFUL HINT: It is also necessary to get Jeff Davidson's Index to the Washeck blueprint collection if you want to save about a zillion hours of looking through the thousands of drawings

Jeff,
Those certainly would make a sylin' transom on the right size boat! The muffler and flapper collar/valves would look great as tribute to PTs. Just not sure what it connects to with that big flared intake :-)
