The picture is a bit misleading, wilko. It looks much better in reality, and is quite a good fit, but the mudguards and stays indeed are pattern parts I suppose (came with the basket case, undrilled and unpolished).
I'll be off to the shed in a minute, then I'll take some measurements on the different tyres I have. But I'm pretty sure the Heidenaus wouldn't fit on an A10/A7, especially at the front, with the reduction for the fork tubes.
