@Bill N posted:...Maybe I'm unique. Unless its a rare item highly valued in whatever condition, then I am inclined to ignore the effect on potential resale value. There will be specific train items that will continue to increase in value. There will be many more that will go for pennies on the dollar, even if we managed to get them used. I am not willing to forgo my potential enjoyment because it might affect the potential resale value years from now.
You're not unique - the enjoyment one gets from a restoration like this far outweighs the few extra dollars that the unrestored version might someday bring (probably when being sold by one's heirs).
And for this particular item, I think it's worth more now than prior to the repaint anyway.
