Hi Reino and Ben, after looking closely at them, I really don't think so, but I could be wrong. I think if the neck and bottom was not so strange on this F1 body with the "dots", I would possibly think it was maybe done to fix a relic grenade. I am by no means an expert on Russian F1's. But I have have found three of these F1's with these marks, and they came from different places. But who knows, anything is possible I would think.
F1's are fascinating to me, It seems endless the amount of variations of bodies. Interesting that many F1's when they were newly made were just a poor casting, and had "pits" in the metal. Many people when they see these "pits" assume this was caused from rust. They were just made and cast this way. It just shows again that the Russians did not care about making grenades and other war items "pretty", just functional.......and also in Massive quantities :tinysmile_twink_t2:
Here are pics of three more I have found that are strange shaped. Also a pics of a few other F1's to show the comparison of the casting quality and shape differences of F1's.
It may be hard to see in the pics, so have tried to take a few angles. I think this filing might have been done when the bodies were made. Interesting the one with flat bottom has a similar very crude looking "wk"? marking as two others in the pics.
I hope I will not be boring everyone with this. I am hoping to maybe learn more from others also.
TO ALL MY AMERICAN FRIENDS OUT THERE.........
HAVE A HAPPY THANKSGIVING DAY TOMORROW!!
