Toothed drive belt for Emco V10 and V10 Mentor lathe. The belt should be 19 to 20 mm (3/4") wide and possibly marked 200XL x 75, iIf so, this belt is correct. However, some late versions of the V10 appear to have been fitted with the 25 mm wide (1") belt from the V10P. If your belt is missing, just measure the width of the toothed pulley. If the pulley is 25 mm (1") wide you'll need the V10P belt that can be ordered here: https://store.lathes.co.uk/parts/drive-belt-emco-v10p-lathe
