The only one's I've seen (or built) were BT-20.
I'll have to scratch build one soon of a BT-50 version.
Do you have a part number or a BNC number?

All the Alphas, Alpha III's and Alpha IV's are BT-50. You're just getting the numbers mixed up a little. BT-20 is the size for 18mm motor mounts (1/2A - C)
I love sanding.
