I see this L-L rifle has been relisted.
I do question the knurled elevation cap on this serial number. Obviously, and to his credit, the seller is surprised to see the knurled elevation cap, also.
The earliest I had seen the knurled cap on apparently original rifles is Jan. '42. This rifle is in the Nov. '41 range.
The gas cylinder may also be suspect based on the appearance of the finish and the lack of staking of the stacking swivel screw.
In pic #44, I believe I do see an 8 in the middle of the follower which would be correct for this serial number. The 8 on the end would also be correct.
The cartouche is GHS small wheel.
I would have liked to have known the length of the stock throat - short or long. It appears to be short to my eyes. Either long or short would be OK but I would have expected to see the long throat at this time.
RCS ,isn't that the earlier clip ejector spring which can be seen in the pics of the trigger group?
