snip: investment casts lugs?, questioned Richard M Sachs...
Living & working in a pro bike shop in southern California, I got to see many of these bikes when new. The early ones had what I gathered were Masi "liberated" or "garage sale" fittings, some even had the Masi BB shell with the M cutout. Some early may Wizard's may also have benefited in this way. Later Medici frames had what looked like "Confente" shaped lugs, with a simpler cut out. The owners of some of the bikes at the time stated they were investment cast. Forks were all over the place, some looked like they were buy outs, & not built in house.
Bought one cheap a while back, it's my LA built bike.
The bulgier.net site has some good catalog scans that sort of show the progression, although some of the photography was pick up from previous years.
