I think it could be from a Boxford, although which model I dont know, maybe AUD ? Others will give you the definitive info.

All (older) models of the Boxford are the same but are Whitworth while the mostly similar looking SouthBend are UNC. So a Boxford one screws into a SB nose but not visa versa.

Hello Mike,

The Boxford mandrel thread is certainly 1.5″ diameter, but is 8 tpi not the 12 tpi on the chuck backplate of this chuck.

Thanks,

Andrew.
