Thanks, folks. It's for sale locally for around a tenner and wings have been cut off below swage line. Photos, show the side trim removed and some surface rust along those areas. I guess rot is likely, though hidden in the seams?. Also no photo of inside seams.
Mine is in good nick and I was only thinking of getting it as a spare, in case of accident damage (girlfriend thinks I'm mad (and is probably right) , especially as would be storing it under the bed).
Think, probably, best to leave it.
