Adaptall II mount for Olympus OM - Just the cost of postage!

Don't know where it came from as I found it in a pile of "junk" cleared out of my brother-in-law's old room in a rented house (along with loads of other peoples's clothes and so on!), and I don't know if it's still working properly but it's not of any use to me anyway.

However, if anyone wants it to try out then I'll post it (UK only) for a couple of quid or so to cover the cost.
