If you are what passes for nuts I wish we all were a little more nuts. I say go for it. Charge full speed ahead and do not look back.
You have done a lot to bring back doubles which were near the point of no return. Restoration often is not economically feasible when you are in the trade. Much nicer to have others absorb the cost or do the work.
I am sure others will consider doing the same based on the results that you have gotten. Maybe not full restocking and full metal refinish in all cases but trying to bring a sound gun back to life is a goal all of us can get behind.
