OKAY FOLKS! SINCE NOBODY BIT ON THE BAIT, I'LL CHANGE THE QUESTION TO " WHERE IS THE TRIGGER LOCATED AND WHAT DOES IT LOOK LIKE?" I KNOW THAT VARIOUS NATIONS DURING W.W.II HAD A LICENSE TO MANUFACTURE THE OERLIKON 20 MM. CANNON AND THAT EACH MAY HAVE MADE CHANGES TO THE ORIGINAL DESIGN TO SUIT THEIR NEEDS. I HAVE AN OVERALL SUMMARY DRAWING OF ONE FROM THE ROYAL NAVY. THE PROBLEM IS THAT MY MODELING SUBJECT WAS USED IN THE THE U.S. NAVY. SOME CHANGES MAY HAVE OCCURED.

The trigger on 20mm guns was a lever device located on the left side of breechblock. The Lambert & Ross book ALLIED COASTAL CRAFT V.II has excellent information and illustrations.....

Hi Steve, I sent you an email with a photo of the 20mm mounted on PT658. In it you can see the trigger assembly. Jerry

Almost forgot that Mike Montana has the booklet "Know your PT Boat online at http://www.pt171.org/default.htm that talks a little bit about the 20mm cannon on pages 20-22. Mike has done a great job on his website, and you will get a kick out of reading this training booklet from Melville! Jerry
