Hi all. Is there a list somewhere of the Hercules engines? I have several ZXB, one ZXA, and yesterday at a show I saw a BXB, cute little engines. When I hear the letters mentioned it would be nice to see what they were. Thanks. Ron Haskell rdhaskell at juno.com Riverside, California USA http://albums.photo.epson.com/j/AlbumList?u=3009370&f=0
