The Universal Fantasy Supplement

Calling All Grogs, especially those from San Francisco!

I'd like some info about The Universal Fantasy Supplement by Clint Bigglestone, friend to the gaming stars of 1970s California. It's not so well known, I'm guessing because actually it's a wargaming supplement. I think it was designed to add a generic Chainmail Fantasy Appendix to other ancient and medieval wargames rules around at the time. It's not a big book, about 32 pages. As far as I can tell there are twenty or so monster types with statistics which use general wargaming tropes (eg. treat as Light Infantry) as well as a tabletop magic system and several different kinds of Magic-User. I'm trying to find a copy and when (if) I do, I'm going to expand this post.
