I have just started restoring a 1976 Bultaco Sherpa t 350. It has matching frame and engine numbers, and I have owned the bike since 1985.  
  
It is fitted with a chrome frame, and I was wondering if Bultaco ever produced bikes with chrome frames. I don't think the bike has ever been stripped before, and it is definitely a standard frame, just in chrome! 
  
Any information would be welcome.
