@Kenny94 Welcome to the family. Hard to tell in that photo. I would hazard a guess its a T140E OR T140D
The "comical hub" front brake would suggest it's from around '71, '72 or '73; the colour scheme is (I think) suggesting a TR6 though it could be a T120 - it's not clear whether or not there are twin carbs. I'm inclined to say single carb. so TR6.
Ask on the other forum as there is someone there who restores the old Triumphs https://triumphmotorcycleforum.com
