I have been looking myself, and I have found prices from $1300 (Cabela's) to $850 at another "gun for sale website" new in box. Hope that helps. If you just Google the name and model you will get lots of info.
Smith and Wesson Model 1
I frame
The model 53 was made from 1961 and ceased production in 1974!
Anywhere from $300 to $550.
100-400 or so
It could be one of many. Impossible to answer without knowing caliber.
100-1000 USD or so
50-500 usd
50-450 usd
Well since that seems to be the serial number on my model 10 revolver, it's worth $269.00. That's what I bought it for.
Needs a call to S&W to find out.
Mid to late 80's
