What Is An 21/28 Overstamp Navy Gun?
Posted 12 March 2004 - 11:52 PM
Since these guns are overstamped, I assume that means they existed as 1921 guns that where upgraded to 1928 specs. That implies that the upgrade was done at the time there was a 1928 model, which I assume is after 1928, or they would not know what to call it.
Did Colt have a bunch of 1921 guns in their warehouse that they upgraded to 1928 models and then sold to the Navy instead of selling the Navy new 1928 guns?
The gun was supposed to be from a police department. Did the Navy sale fall through and Colt sell the guns to the public/police? WHere they sold as Navy contract overruns? Did the PD get it as Navy surplus?

Welcome to the Board. The questions you ask can be easily answered in several books now on the market. I suggest you purchase "American Thunder" by Frank Iannamico or "Thompson: the American Legend" by Tracie Hill. You will find everything a beginning Colt Thompson collector will need to know in these books. Briefly, in answer to your question, all 15,000 Colt production Thompsons were manufactured as Model of 1921. The Model of 1928 Navy Overstamp was made by taking in stock Model of 1921 Thompsons and substituting several different parts, most notably a re-designed heavier actuator, so as to reduce the rate of fire. The number 1 in the date 1921 was overstamped with an 8 to make the Model of 1928 Thompson. It sometime looks like 192B. This modification was initially done at the request of the US Navy and resulted in additional sales of Thompsons to the US Navy and US Marines. The US Navy markings were also added to Thompsons sold to customers other than the US Navy. If you will provide me with the serial number of your 1928 Navy Thompson, I may be able to tell you what police department was the original purchaser. Again, welcome and enjoy the best Thompson board on the Internet.

Basically it’s another Thompson with a few different parts, a slower rate of fire, and a higher price tag.
The 1928 Savage and AO Thompson was the most produced model of Thompson during WW2. Over a million 1928s were produced by Savage and AO. There were less M1 and M1A1 variants made. The numbers are in Frank's book if you want to look it up.
The 1928 Thompson in any variation is the definitive Thompson "look." They take a drum and that look is the most recognizable gun shape in the world bar none.
