Here is a unmarked insulator that is very old and crude it is VNM and was found around Butte, Montana. The only thing I see wrong is two very minor chips at the base of the insulator that were probably there at the begining. This insulator is in excellant shape for one of these. Book is $20-$30 so I will say $20 + shipping. By the way this insulator does not lean the photographer does.
