Hi I am new , have read about every thing here. I'm not a reloader, Collect old tools and show at some shows. I recently Picked up A Star "Bullet sizer and Greaser" With Patent #2,019,795 Which I think I understand.I also at the same yard sale picked up a Potter Duplex.I think The Star is From The 1930's but I would Like know when the Potter Came out .The star has a#7 die in it,And the Potter has #38S dies in it.I have pictures But Am not Smart enough ,To add them,so will have to get my daughter to try to send them.At this I will not sell them Because I want to show them with My tool this Summer.
