Wow, what a neat little bike. NO RESERVE auction will be fun to watch. The 500cc may not be the most desireable, but the bike looks mostly correct (Concentric) to my pre-unit untrained eye, and likely a hard find!
Check out the 57 photos!!

For sure, this is a great find !! KC, this is not a Pre-Unit. Pre-Unit refers to separate engine and gearbox. This is a Unit construction with engine and transmission all housed in the same set of cases, like a H-D Sportster for instance. The Unit Triumph 350/500 series of engines started for the 1957 model year with the 3TA 350 (1957-1969) and with the Unit 5TA 500 starting in 1959 and continued through 1974 with the 500 only, after the 1969 model year .

Funny, here I thought this seller didn’t know what he has.... I didn’t know the unit 500 preceded the 650, now I do!
