Re: More re. Mamiya RB67 - spool
Nowt to worry about. Some brands of film have the "stud"
some don't. i'm useing up some old stock [kodak, fridge stored] that does not. you can use a small piece of masking tape to "anchor" the end down onto the take-up spool.
Depending on the brand of film you use, you should have a "new" take-up spool, with a stud, carried over from the film that is put in now.[remember...each doner take-up spool is
the previous films "take-off" spool.
hope i'v not confused you.[ It's late!]
