IIRC, Bison is Polish. Well respected. Mounts on a
faceplate. Offset screws calibrate it.

Yep, i have a bison 3 jaw chuck that i bought in 1973
and it's as good as new. When ever i need to buy a
brand new chuck bison is my first choice. Very high
quality at a good price. As i recall bison is now part
of toolmex.

Best Regards
Tom.
