There is a lot going on with this one. Bubbles & swirls & a ton of character. There are a few open bubbles from manufacture including one on the top edge of the wire groove. 2 tiny BB-dings on the dome. Some nibbling on the inner skirt base as well as the outer skirt base.

But considering how entirely CRUDE this insulator is, it is in surprisingly good condition!

B on front skirt, No.44 on reverse with a tiny 5 below it for the shop number. This has the most character you can find,

I need to make room. I finally found a green No 44. Will pass on to a new home with love for $60 shipped! Thanks for looking. More photos e-mailed to you on request.
