Some of the parts on my 1919a4 have parts numbers, drawing numbers, whatever you want to call them, that end in "SG". Is that a reference to Saginaw or just a coincidence?

I believe it is in reference to Saginaw Gear, as most of my parts in my gun also have that stamping.

Yes, it's Saginaw

Thanks. Looks like my RSP will get the Saginaw engraving for sure now.
