Interesting stuff, Does 3,639 have an SG stamped anywhere on the left side?
Not that I can see but it's got the SG tang with no locator hole.
I wonder if the receiver ring getting shortened came at the same time that the locator hole stopped getting rounded off? The font change was prior to that according to the serials exhibited, but maybe that's just because of the examples I have suggest it while it may just appear that way due to the order they were being worked.
Here's a little more interest. Note the 3.65 at the top and it's locator hole being rounded, and has the longer ring yet has the squattier letter font of the later receivers.

I don't own one, but always wanted a Saginaw being a GM guy.
Can anyone comment on which CCNLs reference the SG receivers used by Grand Rapids.
CCNL 357-11 discusses the SG and S'G' mixture. Not sure if that's what you are looking for.
Thank you, I saw that one. Supposing about by the manner in which they were assembled was it similar to the regular Prime Carbines? Parts wise, I mean.
I would like to see the right side of the 3639 rec. I think it is just a S.G. receiver sent to S'G' to help them finish their contract. I have S'G' 3637--- and that is what it is you can tell by the way the slide groove is milled. S'G' and S.G. were milled different.
The left side shots show it's an SG receiver since it has no locator hole, also the wide tang. Those do have the different slide groove termination
the need for a S'G' update for the CC club was a project they were looking for someone to do-someone here energetic I will be glad to share fotos of my orig s'g' carbines. and can help with club connections for their data I think
Did anyone yet step up to do one?
Is there anything different/special about a prime in the 3629 range?
Normally, not. They're in the serial range normally associated with S.G.. If it doesn't have the locator hole on the left side it's a transferred receiver.
No locator hole.
Ok, it's possibly one of the SG made ones. From what I've experienced people who know prefer the locator hole style receiver for S'G' just a bit more than the SG one.
Thank you.
What a great post. Thank you for the fascinating information.
Some 1.77s to 1.78s assembled together.
