Early Ti stuff was generally regarded as flexy as hell, especially in the BB, so that is why it never caught on until Litespeed spent a lot of research/development on Ti in the '80s and '90s. Still, even Litespeed had some troubles and a lot of their models from the early 90s are pretty useless due to the huge flex issues.

Teledyne was an early Ti manufacturer and I don't think they have any value except as collectibles of a different era, they wouldn't be much use for riding.
