Colt Receiver Markings
Posted 17 July 2003 - 09:12 PM
Just trying to research what percentage of numbers used each of the different four "1921" configurations.
If anyone has pictures of the patterns I will be most grateful.
Were the Colt frames serialized at all?
It appears that the Colt frames did not have the center ridge running down the area where the pistol grip attaches as compared to the Savage and AOC manufactured frames. Is that a correct assumption?
Sorry for all of the questions but I have been doing research on the Colt weapons and am looking for some accurate info and I always appreciate all of your combined knowledge.
Thank You all in advance,

Were the Colt frame serial numbers in the same location of Savage and AOC under the buttstock slide?
When I am refering to the 4 patterns, Patten date difference, Thompson vs Auto-Ord marking in front of the sight, etc. Doug Richardson's catalog is the only piece of reference I can find at the time. I am not sure if the patterns fell into specific serial ranges? specific dates? or if the patterns even followed numerical order(1st -4th).
Is it also safe to say that Colt Receiver markings were stamped not rolled?
Are there any pictures out there of the difference between the square or round actuator slot?

Colt, 1928/1928A1 Savage and 1928A1 Auto-Ordnance grip frames all have the serial number on the frame in the same location and have what you refer to as the "center ridge." The only difference is the serial number prefix for Savage guns "S" and Auto-Ordnance guns "A.O." All1921/1928 grip frames have the slotted rear grip.
The Savage made grip frames have the "Full Auto" markings on two lines exactly like the Colt grip frames. The 1928A1 Auto-Ordnance grip frames have the "Full Auto" markings on one line.
As far as the receivers, the previous posts are correct, there are really only three variations: (1) serial numbers below approx. 3000, squared actuator slot, automatic and semi-automatic selector markings and Aut-Ord-Co. logo on top; (2) rounded actuator slot, full-auto and single selector markings, Thompson bullet logo on top, (3) same as previous variation except additional Patent Dates after serial number range 14,500.
What is the fourth variation you are referring to? I am not familiar with any other Colt receiver variation. The serial number on all Colt guns was also in the area under the grip mount as Lionhart pointed out. Most, if not all 1928A1 Thompsons had the serial number stamped in the same three places as the original guns: the left side of the receiver, the grip frame and the recessed area under the grip mount.
