interesting S-A 7-40 barrel stamp

[RCS]

I have seen all the 1940 barrel dates but never have seen this variation

Kinda interesting. The distance between the 4 and 0 is not consistant from the first strike to the second or it may be my eyes or the picture. How does the drawing number and heatlot look ?

Paul, the top barrel markings are normal as expected

That is pretty neat
