fuel tank interchangeability

[Dream]

Hi
This is my first post.
I have a low mileage bike which has some accident damage and so I have question to all you CB-1 gurus :- Are there any other fuel tanks in the Honda range that fit our bikes? (or can be made to) I am starting to tune in to some of the subtle differences between them but to the untrained eye, the various CBR range of tanks look dimensionally very similar. I'm sure I will locate a standard tank eventually but thought it was worth asking.

It's not something I'd like to attempt myself, they're such an individual shape that it's never going to be easy to get another tank to fit. The CB-1 has quite an original frame too which makes things awkward. Are tanks really that hard to get hold of now?

They seem pretty scarce in the South East Drew - but i've just bought one now so finger's crossed it's as good as the seller says it is :- £40 posted.
