Topic: New 40mm Single Barrel Bofors Cannon Tech Manual on internet

Hello Message Board! I just checked with the Historic Naval Ships Assn webmaster Rich Pekelney, and he posted the copy of the PT658's 40mm Bofors Tech Manual online now. It is TM 9-252, printed in 1944, It is an Army service manual for this widely used single Bofors 40mm anti-aircraft gun of WW II, This is the same cannon installed on the stern section of a great many PT Boats. However it was removed from the wheeled carriage. The boat mounting ring support may have been a little different on a PT Boat, but I am pretty sure everything that rotated above the geared traversing ring gear was identical to these! It is of great use for modelers, historians as well as for restoration purposes. I think there is a section concerning ammunition in there too. Here is a link

I hope it is helpful to have this information at your fingertips! Jerry
