+ box with matching number. Very rare Alpa with interchangeable finders (fitted with a Miranda waist level finder), effectively a prototype as possibly only 2 were manufactured. Lothar Thewes in ‘Alpa Always Different from the Rest’ (2003) lists serial numbers 56984 + 56998 (this one). Alfred Columberg in ‘Alpa – A Swiss Photo-Camera’ (2004) lists numbers 56984 + 56984a, 56998 (this one) + 56998a & 56998b so it’s possible 5 cameras were manufactured. c.1974
