The Foca URC is a 35mm rangefinder camera produced by O.P.L.-Foca of France. The Marine Nationale variant was supplied to the French Navy, which gives that version particular interest among collectors of military-issued photographic equipment.

With only a single recorded UK auction hammer result for the Foca URC, market data is thin: a Marine Nationale example fetched £720 at Christie's in 2007. That sale represents wholesale saleroom level rather than a retail asking price, and any current estimate of what a Foca URC is worth today should be treated as indicative only given the lack of recent comparables.
