extremely happy to find this odd size of seal in order to complete vintage gearbox restorations. wych bearings do not stock every size, but they get you a long way. quick service, handling and shipping complete a good priced purchase. highly recommended. extra points to be earned if special / custom seal manufacturing would be on offer.
