I believe that I would have bought it. While the price is or seems a little high, it came with the original box w/ paperwork but not tools. However, the tools could be found and added to make it a complete package. At least the box showed that the TT and TH were appropriate to the revolver/box.
As many of us know and have commented in other posts, the guns w/ proper OEM items are more and more difficult to find. OP says the revolver didn't have a mark on it.... Still looks pretty good to me. Are prices falling? I don't know. Out west here, I am not seeing any appreciable decline in prices. My thoughts would be "when will I find another Model 19-3 in very, very good condition, with the original box and paperwork?" An original sealed tools bag can be found. Maybe another $50?
They are never going to come around again like this. Never. The glory days are over. Like the pre-war guns, like the steel and wood WW I and WW II rifles, like the 50's and 60's all steel cars and muscle cars..... I'm just saying that these revolvers are from the last of the "good old days......"
So, for me, I think that I would have "bitten the bullet" and bought the Model 19. I might have spent more than I should have but, in the long run, I would have it to add to my pile or just to admire it once in a while and maybe even shoot it. 'course it's just my opinion, I could be wrong....."
