I've also got the curved spoke pattern. Both types look the same on the outside as mounted but the later pattern has what look like reinforcements and serve as mud/snow slingers. They might also have been used in conjunction with the later hulls which had scrapers on the rear. My hull never had the scrapers but I have a mixture of both types of the curve spoke wheels.

I have a few spares but shipping to the UK would make them cost prohibitive I'm afraid. Sure you can source some over there though is needed.

Ray in New York has a later hull with the scrapers and disc pattern wheels. Maybe he can post a photo showing them for reference.
