After a bit of reading about the M1917, apparently Eddystone M1917s with replacement barrels reportedly have had cracks develop in the reciever ring by the improper insertion of a replacement barrel without proper heating. Given that I have an M1917 Eddystone with a replacement High Standard barrel, I checked my rifle to see if there were any obvious cracks in my receiver. I can't find any obvious cracks like those that have had obvious cracks in the receiver, though there is a line on the barrel and the receiver on the bottom side which I assume are alignment marks.

How prevalent were these receiver cracks? I hear the easiest way to tell is to rub some gasoline on it and looking for any bubbles from seepage in any potential cracks as they may not be obviously visible. I assume with a low viscocity liquid, would Kroil work for this purpose?

Any receivers that cracked when the original tubes were pulled were junked at that point. They learned pretty quickly to make a relief cut in the chamber to release the barrel. The cracking was due to excessive hardening in the Eddystone receivers only.

Probably safe on the receiver, then? When were H-S barrels generally screwed onto these receivers?
