A good friend of mine (the same friend for whose Yamaha SR500 oversize petrol tank i'm selling) is rebuilding a 1936/7 Norton Model 18 for a friend of his. In fact, he's been rebuilding it for some time now, mainly due to a lack of parts, so with my Internet access i'm going to do all i can to help!
The bike in question is this one (click the picture to enlarge):

The crankcase is sadly beyond repair and needs to be replaced. The best photo of the crankcase that we have is as follows (again, click to enlarge):

If anyone happens to have one of these for sale, or knows where we might find one, please let me know!

Thanks in advance, people!
