If you're into weird looking insulators, here is a gem for you from Ohio! CD 110.3 NATIONAL spiral top in light blue. These corkscrew tops are very easily damaged and usually found beat to pieces, this one has one small sliver off the spiral and one small flat base sliver too, that's it. Displays perfect! Book is $150 range. I have pix of the slivers if you want pix. Very crappy weather out today so I had to take pic inside looking out. $90 PP in USA. Now $5O PP in USA.
