Regarding the Brazilian .45s that used left over WW I parts, were the cylinders left over parts as well, or were they newer manufacture with the improved metallurgy and heat-treating?

Thanks,

Bill

I wouldn't think hot loaded ammunition would be a wise choice in cylinders of either vintage.

My guess would be that they used surplus WWI cylinders from the number reported to have the Defense Acceptance stamp(eagle's head) markings.

Improved metallurgy or not, I agree with arfel. Hot loaded .45 ACP or Auto Rims are not a good idea in these vintage revolvers.

Thanks for all of your thoughts. I agree hot loads are inappropriate. My concern is not hot loads but rather reports that WW I cylinders have failed with standard pressure loads. While + P may be out of the question, I see little point in spending a lot of money and effort to fashion a carry revolver that can not safely handle standard factory ammo.

John Traveler, that tip on the Defense acceptance mark is most helpful. Looking at the cylinder from the rear and the serial number at 12 O'clock there is what appears to be three very small numbers at the 7 O'Clock position. To my tired old eyes it appears to be 524 or 324. I don't think it is an eagle's head but I could be mistaken.

Thanks,

Bill
