FYI, these bicycles were imported during the early 1970s bicycle boom by West Coast Cycle Supply who was most famous as being the owner of the Nishiki brand. Based on the rear derailleur, the bicycle is no newer than 1976. The skip tooth arrangement facilitated shifting on large cogs, where a high number of teeth engaged the chain.
Caloi received a huge recognition boost in the 1990's when the 1995 & 1996 Motorola pro teams rode Caloi bicycles. Note the small "by Eddy Merckx" decal following the Caloi logo on the tube tube in the attached scan.
