My 22/32 HFT with s/n 224963 shipped September 20, 1915. My original box is similar to yours, and like you I had "guessed" at dates which were all over the map, even looking at SCSW, so I went ahead and sent for the Factory Letter.
Charlie, very nice example with box and letter. Just one small FYI, the letter states that Bekeart received 292 from the first run of 1,050. The correct number is actually 294.
The shipments were as follows:
6/7/1911 30
6/22/1911 60
6/28/1911 60
6/30/1911 60
8/31/1911 50
10/31/1911 34
Total 294
In my database, I have all of the serial numbers for the first run of 1,050. Unfortunately there are a few without dates or destinations due to the dreaded "open on the books" or unreadable in the hand written records.
This is where the Bekeart mystery gets funky. Bekeart is credited with this new revolver design, a .22 on a .32 frame and supposedly had to order 1,000 to entice S&W to do the tooling required to make this new model. However, as stated above, Bekeart only received 294 of this first 1,000+ run and although he received the first shipment of this model on 6/7/1911, other S&W distributors of the day began receiving shipments as early as 6/16/1911, or 9 days later. So early on, either Bekeart or S&W realized that he would not be able to sell all 1,000+ from the first run.
What adds to this mystery, is that there is an ad out there by Bekeart where he claims to have a second exclusive order of 1,000 of this model available for sale. Not sure if this was just salesman's puffery or what but I don't see that amount going to Bekeart in the second production run of 1,000 or so guns.
Granted, the first 1,050 guns worth of information was transcribed by me from the factory records through the grace and cooperation of Dr. Jinks in his home office. The rest of the entries in my database were scrounged from online auctions, ship date requests on the SWCA forum and posts here on the forum.
After the 138XXX and 139XXX guns from the first run, the next block of serial numbers appears to be in the 161141 to 165954 range. This appears to be a spread of almost 5,000 serial numbers. Since these number blocks were shared with the .32 caliber arms, there is no way of telling how many .22/32's were actually produced in the second run or how many went to Bekeart. Of the 100 listings that I have in this grouping, 53 went to Bekeart so more than half.
Therefore, the more information that I can collect, the more clear this story will become.
Keep them coming!!
