People here have been great with answering my questions and I greatly appreciate it. Where would you place the value of this pistol if you were sellling it? TIA My friend happened up this rifle not long ago and I was curious if there is any reason not to modify it (i.e. scarcity). It is in overall pretty poor condition finish wise, including where someone apparently tried to wire wheel/brillo pad/steel wool it, but mechanically seems really sound. Can anyone tell me year of mfg? Are the English Proof'd ones scarce enough to leave as is? He wants to send it off to have custom work done (sights, refinished, a few other thing). Here are some pics.
