as far as the brand of hardtail,i really am not sure.
it's an old alloy nickle or chrome rear section.
some have said it to be an old "Trackmaster" section,and some have said it to be an old "Burbank Choppers" rear section.
anyone's guess is as good as mine.
Trackmaster didn't make rigid bolt on tail sections like this (while they DID make some complete hardtail frames they wouldn't have made one that was 4" over. Dirt track race frames have to conform to AMA rules and it would have been stock length if anything. Sonicweld made rigid dirt track frames for Triumph 500's but again, they would have been a complete frame not a bolt on, stock length and the axle plates are totally different.
Just trying to help. Also, did the carbs show up in the mail yet?!??!!?
