For my own use, I would restore them to working order but probably not to ‘as good as new’ look.
First I guess it depends on whether you plan to use it or display it.
Is there a general rule to this or are there two schools of thought amongst collectors ?
I ask, because the flea market here has a lot of old tools for low prices, but i don’t need them all (yet).
The antique market here has some old tools for higher prices but not much, if anything has been done to them apart from cleaning.
I was wondering if I might be able to turn a profit restoring old tools to sell to collectors that probably wouldn’t use them. Not sure if those types of collectors prefer the tool to look old.
