Restorers, want to get it back to original. This is period correct as it shows .9L capacity rather than 1L which was stamped on some later models.
Good condition with a useable gasket just needs cleanup. Purchased from an old line Honda dealer who stocked lots of OEM and high quality replacement parts in the heyday of Japanese imports but is now closed. NOS Items may have shelf wear, metal items may have slight corrosion, but pictures taken from all angles and you can ask questions about condition before purchase
