Thanks Kenny,
I think it is a Herters "Model Perfect" Automatic Seating Die, the caliber marked on the sleeve and bullet seater is ".300". I put a .30 Cal case in it and it is not a neck sizer. It is not exactly like a Herter's as I can't match my photo with any of the existing Herters photos but the sleeve and seater portion resemble the Herters a great deal. But hey I'm getting closer. thanks again for your help and same to others that have responded.
