I'm glad to see an accepted reference that supports my decision not to have a patch box on mine, after all the grief I got for mentioning I wasn't going to have one.
I agonized a bit over that same question. My original plan was to build a replica of the Bogle rifle as illustrated in Ron Borrons drawing. I just could not find a source of absolutely correct hardware without custom hammer work, which I can't afford . So, my build is pretty much turning into a genralized, sort of, kinda like Bogle.
But in looking at some of the basic steel patch box kits I think I can pretty much match the patch box as illustrated here:
