Tuga Dude, as promised, here's a partial scan from what I believe to be 1979 or 1980. Please note how Technart is used to describe the both the hi-tensile frame of the Skyway 12 and the stainless steel frame of the Submariner 12. There is no mention of Technart on the traditionally brazed, mid-range, Diamond Formula 12. As stated earlier, Technart was the actual tube joining process and had nothing to do with the employed tubing material.
Also note that the Submariner 12 is spec'd with a Technart, hi-tensile fork.
