CD133 there, if it has any embossing, 99% chance its a Brookfield. Looking closer at the shape, i'm gonna say no embossing on it, which would make it Canadian. That's a good find, in good shape probably $30 or 40 bux.
One thing I will say, do not let the condition have the final say. There are some insulators out there, and damaged is the only way you could ever hope to own one, if even then.
I'd guess same time frame as your other. Its possible a nice big fat threadless could be laying around there too..
Thanks for sharing..
