Carpet squares (Southport PR9)

We have +/- 50 rubber backed carpet squares size 51cm x 51 cm (approx. 20" square) plus several smaller pieces. They are mottled with various colours but predominantly dark blue and are from a couple of different batch numbers so colours vary slightly. Would be fine for playroom, workroom or any place where an exact match is not critical. They could even be used as underlay. Sorry but I cannot upload a photo.
