The Ricoh KR-10 is a 35mm SLR from the late 1970s, sold in some markets under alternate names including the XR-1000S. It used the Pentax K bayonet mount, placing it within the broad K-mount ecosystem alongside cameras from Pentax and other licensees.

Sales data for the KR-10 is very thin: a single UK auction hammer result from April 2025 sold for £12, which sets the only firm reference point for what one is worth at saleroom level today. With just one wholesale data point available, that figure should be treated as indicative rather than a reliable median, and clean, working examples with a lens may sell for more in the wider market. As a rough guide, a tidy body without a lens tends to sell for low double-digit figures at UK auction.
