Sorry for the non A7 - A10 post, but my mate is contemplating making a bid for a basket case BSA A50 ROYAL STAR 1965. Apparently it's rough, but all there, except barrels, no front wheel only hub.log book lost - a full restoration job. I'm not currently up to speed on prices, what would be a reasonable offer price for one in such condition (£ sterling).
Thanks
Brian
