What model of Hollywood press? The senior or the universal? As far as shell holders go use the H press adapitor from RCBS or C-H, it is mounted on the ram and standard shell holders will snap ringht in.
Just do a google search for hollywood loading press and much info will come up about the press and the present owners of the company.
At one time the Hollywood was considered Thee press to have, strong and could almost any type of reloading on it. They were not cheap presses, built of quality materials of the time.
The press I really would like to own is a Universal from the late 30's as they were made from cast iron.
