The Alpa 10s is a 35mm single-lens reflex camera built by Pignons SA in Ballaigues, Switzerland, introduced in the late 1960s. The black-and-grey finish is one of the rarer cosmetic variants of the precision-engineered Alpa line, which was positioned as a high-end alternative to the mainstream Japanese and German SLRs of the period.

Auction data for this specific finish is extremely thin: a single UK hammer result of £1,800 from 2016 is the only record on file, so a meaningful price or value range cannot be established for today's market. With only one verified sale, any quoted figure should be treated as indicative of what a clean black-and-grey 10s sells for at saleroom level rather than a settled market median.
