Like a lot of things selling was probably not an initial consideration.I would think you"ve also made it harder to attract buyers.
On the same site a nice Series 70 Gold Cup was up for sale - and while originally blued it had been re-coated with hard chrome/nickle process.
It was however priced accordingly given the modification ($750 and sold quickly) and quite frankly looked pretty good. In this case the value was hurt but the gun was still in it's original configuration so someone got a very good deal and I am sure there were many in line to buy it..
In the case of the Henry I can't see many wanting a SS modified in the manner it is.
