Send in the data sheet to the Carbine Club. I think you will get confirmation on your safety. A friend of mine told me about one he had with only imporperly marked safety. I told him he should leave it alone for now. We later found one in the Carbine of the month with the same safety. Bill
I've heard the same thing and that the numbers ran from 2 to 7 - also that it was done after installation of the sight, and was to aid those those targeting the rifles in filing of the front sight blades. Does anyone know for sure if the 2 represented a sight that needed to be shorter, or was that maybe the 7? My sight, marked with a 7 on the left base is really short at around .2 inches, but I believe someone has done some more filing on it since 1943.Quote:

Do you know where on the inside they usually put the marking? I can't find anything inside on mine. I'm curious too about Mikey51's sight - another "sidewards N" variation? On an S'G' ?Quote:

It was Irwin Pedersen not Saginaw Gear that initiated the front sights of varying heights. IP precut front sights down from the standard height to one of seven dimensions and stamped a corresponding number on the left side of the sight. When the carbines were targeted they were done so without a front sight. Instead they used a dummy fixture which gave them the height required for the front sight blade. After targeting the appropriate pre-sized front sight was installed. The IP pre-sized front sights ranged in size from 0 - 8, with 0 being the tallest and 8 being the shortest. The #1 sights were the standard height of .795" from bore centerline. When Saginaw Gear took over the IP facility they abandoned the practice in favor of the standard method of firing the completed carbine, then filing the front sight to the appropriate size. Saginaw Gear did use some of the left over pre-sized front sights but they were targeted in the standard fashion.Quote:

It's beginning to sound like the "N" and the "sidewards N" are both correct for the S'G' also, since mine has the leftover IP sight and Maniac's is probably the later version. - Bob
Brian is right. The PN sight has a 6 on the left side. An all IP part gun except for an RMC handguard that I can't explain. I have been trying to attach a pic but the system won't work tonight. Will try again tomorrow, Mike.
Really informative post. I will start looking over my all S'G'. Where do you get this information sheet? Enjoy your M1 I enjoyed all the M2's I used to get for $20 back in the day,'67, when I was working for MACV/SOG Kontum unpacking tons of WW2 arms. I received mine in a two gun deal from a guy who needed bail. Note to self; don't poke the old lady in the nose when high.Enjoy your toy.

Here you go guys. The side of the PN sight on a 1771XXX. Cheers. Mike.
Robert Irwin made stocks were commonly found with the green number stamps inside the stocks.
Inland did the same but their ink color was different and thought to be a dating system (Julian).
Irwins numbers were thought to be part of the production codes/ steps/ inspections... etc.
