saeco sizing die

[jms1911]

I have acquired an old Saeco sizing die in 454 dia. It looks like all my others but has no threads on bottom. Did Saeco make a luber-sizer that held them different. I have never seen one like that. Can anyone tell me what I've got? John

I have a SAECO luber sizer and on mine the sizing die is held in place by a screw on top and to the left of the die. When I made my own dies I never felt the need for threads on the bottom of the die so I left them off. Works just fine.
