OK, not being a .22 caliber then we have determined that the OP's gun is not a .22/32 HFT. Since the .22/32's and the .32's both used the same serial number blocks I checked my database and the closest HFT that I have is 444752 and that gun shipped 10-7-1926. The next one listed is 454453 leaving a gap of almost 10,000 numbers so plenty of room for a run or two of the .32 HE's.
Initially begun in 1911 the HFT's came with a Paine front, U notch rear and the 2 screw over sized target stocks with gold medallions.
Regulation police style stocks with the gold medallions begun to appear in mid 1919 replacing the 2 screw style however by 1921 are replaced by the regulation police style without medallions.
On 8/29/1923 the engineering change to go to the Patridge front sight, square notch rear sight and the 2 screw extension target stocks again replace the smaller regulation police style stocks. Probably due to on hand inventory this does not become the norm until 1924.
Non medallion stocks remain until roughly 1930 at around 500,000 serial number when the silver medallions appear.
The only other issue that I am not clear on is when did the .32 caliber guns move from the I frame to the K frame. IIRC the K 22 was introduced in the 1930's so unless the K frame .32's came out earlier, would the OP's gun be an I frame?????
My short term memory is turning to mush due to my cancer drugs and I find that I have forgotten more than I remember.
