Starr blackpowder revolver
A friend of mine showed me her late husband's firearm collection.
Very interesting, there was a S&W single shot .22. Sort of looked someone had shaved the sides of the cylinder off of a revolver. One that interested me was a Starr blackpowder revolver, ser. no. 39539. The other marking was Jan 15th 1856.
There was also a large knife collection that I will catalog for her.
She wants to sell the collections for her son. How would I find the value of the Starr revolver?
