Antique Parts

Welcome Adrian.
Lots of dealers your side, try these Chaps, they understand their vintage Brits as they actually ride them too

Not quite antique yet unless you also have one of those 1902 Triumphs as well as your T140D

 

Hi Adrian, from another Adrian!

These people used to have a reputation as the biggest stockist/supplier of old Brit. bike parts in the lower 48. Iowee's not exactly next door for you but they do have a huge online presence so worth a try.

BTW, we normally need photos of the new purchase .......................................

 

LOL, probably because there's a Vintage MCC over here formed a few years before your Antique MCA.
Antique is really anything over 100 years old, and as we invented the language..... Antique is ok with me but I wouldn't want to call anybody's T140 an antique, the T120 owners would only get jealous. You know what they're like - small conrods and all......

 

my conrods are longer than yours
