I think you have to consider each gun individually; for instance a couple of years ago I bought a 16ga L C Smith ejector field grade that had been poorly restocked but otherwise was a sound gun with very little original finish for 450.00. Just restocking it didn't make sense so I had Ken Hurst engrave it, Classic Guns recolored it and reblued the barrels, I am stocking it when I feel like it. When it is finished it will be the equal of almost any Monogram L C made, priced one of these lately in a small bore? I know I would never be able to recover the expense of redoing this gun but it is what I want. In another case I have a 20ga field L C no ejectors, factory 26" barrels, 2 3/3 chambers; it has a lot of case color, almost all of the blue but was minus the stock when I bought it. I just happened to have a nice original stock, so it makes sense to fit it to this gun and make a nice profit. This is where my signature line makes sense
