I own and IBM AO with a SC B  Birch stock.  On my "Grand Entrance" Thread, New2Brass, ask if I had checked under my rifel buttplate and seen any markings as quoted here.  I explained that I had removed the buttplate during cleaning, however, did not pay any attention for markings there.  I checked and upon inspection I found the following:

Between the Top Hole and Middle hole there appears to be the number 5
Between the Middle Hole and the Bottom hole there appears to be the number 4
3 Pictures - Please see Link Below  

Haven't quite figured out how to downsize my photos to get under the size restriction, I posted them for viewing on Photo Bucket.  Please examine and let me what you think, and possibly what they may mean.  My conjecture would be the Stock MFG/Milling Line and Inspector Number.  However that is pure speculation with absolutely NO Proof.

Anyone ever see an upside-down AO on an IBM? Serial number 3845907.

Maybe a good spot to put up pictures of 2 odd Butt plates I ran across years ago and still have.

This 1st one came on a WRA type III stock with the Korean paint job on it.
This is also the Recoil plate that was on it. Shortly after I pulled more Korean returned GI stocks that had the same style Recoil plate on it. Another Recoil Plate had a square lug on top. Still looking for that picture-






Butt Plate Stamped Upside Down (?)



Found the Square Lug Recoil Plate:

Edith and Estelle teamed up to work split victory shifts
Edith worked Tuesday night when the logo direction changed happened. 
Estelle on Wednesday night,  not knowing the change happened and stamped them horizontal.

Her sharp eyed supervisor caught this right away and informed her of the change. She took the handful and restamped them to the new specifications.

There are only 7 out there, I call dibs on the next one!Clown

Makes you wonder what the rational was for changing the Inland logo from horizontal to vertical that they thought was important enough to Change this one.

Bill,
Yes that is why I asked about the comma thinking that it may have been an earlier scrapped receiver and then reused with a later serial. Whatever the case it is interesting.

No comma. All NPM 'U' and all UN-QUALITY receivers that I've seen have the comma on the front ring. Quality H.M.C. carbines also have this front ring comma up to serial number 1621877. QHMC carbine 1633386 and beyond do not have the comma. Somewhere inside this range of serial numbers is where the comma went away. Newsletter 380-19 has a short blurb on this "comma question".
SF,
Bill
