A question for you people who've owned the '35 and '30..do they share the same fuel cap? Mine (NC35) is currently jammed open, with the key in it (fortunately I have a spare). Despite overdosing on WD40 etc it won't loosen off and click shut, so I could be looking for a replacement. There are a ton of Chinese copies around but I'd rather go for an original. Thanks.

Got one! From Graeme France. Excellent condition. 2 new keys plus original. £45.
