why would the letter M in the word model of 1917 on the receiver be notched out like they drilled 1/2 of a 1/4 in hole. can email a pic to you if you could help. it shoots great dosent affect the function just looks strange
Some surplus M1917s were returned from Europe with a notch machined in the receiver in line with the chamber. No one has come forward with the exact reason but there is speculation that the notch was to allow clearance for machine gun cartridges with heavier (therefore longer) bullets that may have fowled with the top of the receiver during chambering.
