I've checked my stash of spares and managed to dig out some spare axle's ;
They are £15
each plus postage , email me if you're interested and I can get a quote from the post office. Posting abroad is not a problem but it does tend to cost more (Post Office charges).
Price is for bare axle & sprocket only , no wheel nuts or brake components etc included.
ps - willing to haggle on the rusty one....it is a bit scabby
