Altus A10 rear mech

There's one just gone on UK eBay that looks to be NOS, if not I've got one available for the cost of postage. Came on a project bike, so I can't vouch for how well it works but it's complete.

Just came across that NOS one myself and already contacted the owner.
He has a NOS crankset on The Bay too, so I'll probably buy the lot of him IF he's willing to ship internationally.
