Al, I dunno why the email address is acting up...?
It's not a complete taper attachment, just the extended cross slide with slotted tail that is part of the complete taper attachment...witht he gib and screws and etc it's an AS485NK1, but this is just the casting.
I do also have a complete taper attachment I've never used, but the day after I let it get away I'll have a job come in that needs it, you know how that goes...
I can also be reached at brianpsherwood at gmail dot com
