Friends-
I have a question regarding the duck-ponds in M-1917's and P-1914 rifles. I think I read somewhere, where, Eddystone's and Winchester's all had the duck-pond milled into the receiver. I have also read or seem to remember that as for Remington produced rifles that the duck-pond was a "mixed bag." Some had duck-ponds and some didn't?
Is my understanding correct and would someone possibly offer some official commentary regarding this?
Thanks in advance.
Mark
