I mistakenly purchased a copper head gasket for a 1937 BSA M20 from Copper Gaskets unlimited in the USA. Hence I have a head gasket I don't need. Please note that this is the 8 whole/stud head gasket not the ten whole.
With shipping it cost me $36; I'm trying to recover most of this, so I'm willing to sell this item for £20, which includes Royal Mail 1st Class 1 day deliver,within the UK, which is £1.40. Let me know if you require it to be sent to another country.
If you are interested send me an email and we can arrange payment details.
