I just called Elderly, and they said it is TOP (temporarily out of print). I think that means it is POP. They're still out there somewhere, I'm certain.
Thanks, Paul, but no - it's not what I'm looking for. Converse's titles are confusing. There is the 'Banjo Without A Master' and 'Banjo With Or Without A Master', both from the same year, 1865. I have the former but not the latter.
The book advertised on that site is tab versions of some of the former. Plus, I'd MUCH rather work from a copy of the original.
