Might have a lone MIJ 20" kicking about in the shop. I can't recall if it was 6 or 8 lug. I personally planned to drill new lug holes for it as it came with center lugs ( which were busted ) just never got to it. The inside at some point had been filled ( or attempted to be filled ) with wood filler. Most of it is gone, but still a bit of a project. I'd only want $20 for it.

Thanks for the reply. The idea is to make my Royce set more suited to low-volume gigs with a 20" bass. The less i need to do to it the better. So a 70's-early 80's Pearl or stencil would be ideal.
