Research Assistance
Saginaw Receivers
3,249,020 thru 3,651,519
5,834,619 thru 6,071,188

We are researching changes in receiver features in an attempt to identify when these changes took place. This also helps to reconstruct some of the shuffling around between the two factories. Much of this information has not been previously requested or reported due to the size limitations of a datasheet.

Your assistance with this research would be very much appreciated.

The answers to the questions that follow and/or pictures can be posted here on Milsurps or at this link on The Carbine Collectors Club Forum: Club Assistance Saginaw Receivers - The Carbine Collector's Club
Alternatively, the information and pictures can be e-mailed to the following Club e-mail address:

SN@USCARBINECAL30.COM

You can also submit a full datasheet. A datasheet can be downloaded and printed from here:

http://uscarbinecal30.com/forum/uplo...v4__1-1-11.pdf

Please note: if you have previously submitted a datasheet in these serial ranges, we ask that you carefully review the information that we are looking for. We will then update the datasheet on file with any new or missing information.

For your convenience: at the bottom of this post is something to help you submit your answers. Simply copy and paste that information into your e-mail or forum post to respond and fill in the information as you read through the questions.

Question #1:

What is the full serial number?

(If you must provide a partial please use two lower case x's for the last two digits. Example: 3250020 would be 32500xx.)

Question #2:
Above the serial number are the letters S and G. What are the characters following each letter if any?

S.G. S'G' or simply SG

Attachment 108744

Question #5:

At the rear of the left side of the receiver there may be a feature unique to Saginaw we refer to as an "ear" (left & center below).

Does your receiver have a rounded ear (left), squared ear (center), or no ear (right)?

Question #6:

There may or may not be letters and/or numbers on the left side of the receiver. If present what are they and where?

Examples include SI or SG. There may or may not be an additional letter and/or number near the middle of the left side. Please indicate all that are present

Now I wish I had one....

It'll be incomplete if they don't note if the SG is small or large letters on the side of the receiver. IMO.

tenOC, What is the size difference between the large and small SGs? If I only have one that is marked SG on the left how do I know whether it is large or small?

Saginaw plant used the large 3/16 letters first and then went to the smaller 2/16. There are also Saginaw plant receivers with no letters.
the change in size of letters took place in the 3,340,xxx to the 3,458,xxx range. That can probably be narrowed down further.
The information can be added to the survey question #6 response. It is better to have the information rather to have to look for it.

Good point. We need a pic too. Maybe it's covered enough in previous letters. You guys know them better than I.
