Flanged rim sashlocks (Fulbourn CB21)

Four nearly antique door locks. Rim sashlocks, a common size 4" x 6" each with its keep. Probably 1920s, with what was once cream paint. No keys, but these are not security locks and any locksmith should have a box of plain keys to fit. No spindles, fixing screws or doorknobs.
