Some things don't change...
Guns are worth what someone is willing to pay. The trick is to find the person who wants it most. Blue Book of Gun Values is a good start as a background, but regional differences can alter those values.
I would suggest you explore posting these guns on one of the on line auction sites. That will give you exposure to the greatest audience who may be interested on those particular guns.
New in box guns - even of relatively 'ordinary' nature - are always sought by some collector. For instance, the nickel Model 39 appeals to me, but I'm currently in 'slow cash flow' mode. No doubt someone could outbid me handily for such a pistol.
The best of luck to you, sir.
