My decal indicates tru-wel tubing was made by Ti, or part of the Ti group. It's history before that I do not know. I know of 3 different grades/types of tru-wel tubing; (probably lower end) 205 I have on my frames, 201 used on the Carlton Ten and (higher grade?) 40 Wel offered as a built to order option on the Carlton professional. I presume there produced more than these. Here's a couple of links to a Cartlon 1970 catalog; http://bulgier.net/pics/bike/Catalogs/carlton70/06.JPG I have a Cobra which has a 205 decal http://bulgier.net/pics/bike/Catalogs/carlton70/07.JPG You can see from the fuzzy text the pro has a choice of tubing, I have seen a price list from the time and the 40 Wel option was more expensive than the 531 although that doesn't mean it was necessarily better but it was probably more comparable. I believe that other manufacturers that used tru-wel tubing included Raleigh and Dawes although which grade and for which end of their line I do not know.

There were the teams; Carlton-Truwel (although I think in full this was Carlton-Truwel-Campagnolo) and Sun-Truwel (Sun-Huret-Truwel). I presume that Tru-Wel was quite strongly linked to the Worksop factory but I know little more that that.
