Some nice photos. The 20 is like one I have completely re-done, except my guns have sanded in oil finishes that are not glossy. The one thing not mentioned is the stock dimensions...other than adding recoil pads. I've seen a number of these re-done guns which look fine but shoot shitty due to bad dimensions. I think the first thing to contemplate is the stock. Will it fit you? If not it's all just fluff. Fox stocks can be bent to decrease drop and add cast. That said, it's probably impossible to get one up to modern drop dimesions if you start with 3" DAH. I have two Sterlingworths bent from 2-3/4" DAH to 2-1/2"... they fit me much better and are good shooters. Have fun!

Cheers!
