The Alpa 10d is a 35mm SLR made in Switzerland by Pignons SA. This red-and-chrome variant belongs to the Alpa 10-series produced from the 1960s, positioned at the upper end of the precision-instrument SLR market when new.

Sales evidence for this specific red/chrome 10d is thin: a single UK auction hammer result of £1,700 from 2016 is the only data point on file. Because that is a wholesale saleroom figure rather than a dealer asking price, what one of these is worth in 2026 cannot be reliably narrowed beyond that historic sale, and condition, completeness and originality of the red covering will heavily influence what it sells for today.
