The original Hollywood Gun Shop reloading equiptment dates from the late 40's thru the 50's. Maybe into the 60s?
I don't think I've ever seen a carbide sizer with their name on it, but you never know. Just check for the 'ring' insert on the bottom edge/mouth as 'ronnie gore' says.
There is a current (I think they're still in business?) Hollywood Engineering Co. that is a different outfit from the original company but they say they support the older presses, etc with parts. Also makes new presses.
Don't thnk they make or market dies. But if they do they'll have the 'Hollywood Engineering' name on them instead of Hollywood Gunshop.
Lots of unsatisfied customer reports about them but I've never dealt with them personally. Located in Sun Valley, CA.
