    Posted: Jan 12 2021 at 7:10pm
In War Baby, In the summing up Saginaw's Carbine Program,
In the stock section page 435, Larry mentions:

Type A, Variation 1 with the I cut Oiler Slot (Type I) was found with RMC 40 A

Type A (M1), Variation 2 with Oval Oiler Slot (Type II) was found with sling well marking of OI 40 A.

Type A (M1), Variation 2 with Oval Oiler Slot (Type II) was found with sling well marking with upside down U and a 7.

Type A (M1), Variation 2 with Oval Oiler Slot (Type II) was found with sling well marking with RSG and 9 A.

Type A (M1), Variation 2 with Oval Oiler Slot (Type II) was found with sling well marking with 75 E RSG

Type A (M1), Variation 2 with Oval Oiler Slot (Type II) was found with sling well marking with RSG 88 F

Type A (M1), Variation 4 with Oval Oiler Slot with modified slide clearance cut and was found with sling well marking with RSG 105 B. This one noted use during late production.

There is no mention of Serial numbers ranges to the letter/number codes I could find.
Which leads me to think he was just using observations from examples he looked at.
Am I wrong ?
Where was Larry heading with this information? Did he believe the letter/number codes used by Saginaw SG had some rhyme and reason to them, maybe a increasing number and letter as production moved forward ?
IF Based on increasing number/letter codes... Could these have been based on Deliveries as accepted  by SG?
I've often thought the added markings could have been applied by a In House Stock Inspector at Saginaw, before assembly commenced in that stock. Assume they would have inspected deliveries and possibly used different gages and jigs to inspect them with. Maybe numbers/letters were related to order numbers/invoices. Letters to a inspection section and or shift.
I think back to the picture of a Robert Irwin worker checking the actions fit in a new made stock.
And would think SG would double check before wasting any labor on a stock to be found later to be out of spec.




There is also no mention of the Type II TRIMBLE TN stocks that were used by Saginaw SG.
2 examples pictured below.

I'm asking because I happened across a older post on Milsurps today from a member in Europe that showed his SG 3.37M that appears as Original.
His Sling Well is marked 1 digit below the 2nd example listed above of OI 40 A.

Here is SG 3,37 mil with OI 39 A in the Sling Well:













Has there been any Updates I'm not aware of with the Letter/Number markings found in Saginaw used stocks ?

Thx,

5,86X,XXX 
Was featured in CCNL 356 and has the following noted on its datasheet  https://imgur.com/Povbck8
RSG
G
105

So there's another serial number to associate with those markings.

Are those Trimble stocks associated with SG receiver numbers?

FWIW the 105 that was in CCNL 356 is a Type III or a Type II cut down.

Here is one more stock to add to the listing.  It started life as a Type II, but the high wood was removed at some point.  Has a faint, but recognizable SG cartouche on the right handside.  When I purchased it, it held SG receiver #33288XX.

I think that may be a 7 not a 1, 7 with a line through it, like the old days?

I Zoomed and even had the Wife and her friend look at it for other opinions.
First they thought a 7 with the line thru it. But when looking closer it looks like a 1 with the top squiggly that has been double struck or rebounded.

Though not a very good picture above I have a picture of one of mine that has the TRIMBLE over TN,
with 41 and a B stamped over SG. If you look closely the 1 in my 41 has the same top detail as Jim77's 
51 A. Top of the 1 have a sorta ~ to them.

I also noticed Jim77's picture file was titled 51A, so I believe he thinks so also.

But It can be changed if I see a 7 has the same detail.

Thx
Charlie-P777

ETA: I just pulled out 47E and the 7 has like a Serif top to it, looks nothing like the 1 pictured above.

Yes Charlie, I just zoomed in on it, agree a double stamped 1 not a 7.

Didn't mean to cause so much controversy.  I have always thought it was 51 A, with the 1 being a double strike. I should have stated that. If true confirms they used individual number dies to apply these markings. Hopefully this new picture in brighter sun resolves the issue. Appears first strike was slightly off to the left.

COM 281 stock is I-cut, low wood.  The article suggests it may be a "floor sweep" carbine, made from whatever parts are available at the end of production.

This SG stock and receiver looks like they are the original mates? Unfortunately can't see the first part of the serial number.  :(   Possibly a wide tange receiver.

I suspect that's a Bavarian number, unless I am missing something.
