Great find!
If you look on the ends of the boxes,, you will find the model info on the label.
That is,, if those are the original boxes.
That said,, the top pics show what appears to be a blued Old Army,, and a short barrel. It should be a model "BP-5F" by what I see. And the stainless one,, a GKBPI-7F.
If those are correct,, a factory letter for each one would prove what model they are. And since the fixed sighted guns are scarcer than the adjustable sight guns,, PLUS,,, the short barrelled one is also scarce,, the letters will prove what they shipped as.
The letter will also give the shipping date, the mfg date & where they went initially.
Values depend upon these being shipped as the models I mentioned,,, AND the overall condition. The pics aren't clear enough,, but they both appear to have been used some. Condition is paramount. And especially the internals of the barrels & cylinders.
