I get your gist Ralph, but you might be a tad severe about the condition of the gun. True target revolver collectors would not even buy this one for parts, but to someone who does not own a shooter 38 Target, might be appealing. There is just nothing you can do with that left stock and maybe the right one is OK?? If both are bad, replacing the stocks could cost you over $100.
This one has been back to the factory for something and in the old days, that usually included a factory refinish. I believe the factory would have also added target sights if the customer wanted them installed, so would not think it started life as a Target revolver until I saw the letter. I think I see a grooved trigger, which may also indicate a target model, but not sure?
Bottom line is a decent shooter grade standard 38 M&P from the 1920s is worth at least $300 unless it is really a beater, so you have to determine what the target accessories add to the value for you.
Only example I have of a 38 M&P Target near yours is my 482,XXX, 6" in 95%+/- original finish that shipped in Feb 1925. I paid $400 for the gun last year. If you are in no hurry and regularly watch lots of online auctions and visit lots of gunshops, you can find a bargain, but it may be quite a while before one shows up.
