I bought these ages ago as a backup scale but no need for them now as I have accumulated several scales over the years. They have never been used and are, as you would expect, unmarked and come with their instructions. The box has seen better days but the scales are spot on. They are magnetically dampened and adjustable for levelling. Price £36 posted. Pictures below.
