N marked front sight question

[painter777]

I didn't know if a certain style was used then changed over time

IP, S'G' and SG all used the Type I Milled front sight. Which was milled from one solid block.
Some other makers later on used the Type II front sights, when they became available, these we call 'Fabricated' and supposedly quicker and cheaper to make by stamping and brazing together. These were made of multiple pieces.

Your N sight is legit, just not often seen milled that way. There was a War on, Carbine production was deemed critical.......So no one was really worried about being pretty.

I found a N marked front sight currently being offered on a Auction site. Appears to have the same 2 grooves, just located farther forward.... See pic.

PS: Just looked at your GALLERY PICTURE. It shows a number 7 on the outer left ear. Be nice to see a Size / Font Comparison on that #7.
