The greenburst or redburst electric 12 was definitely the first of the Burns guitars to be used in public by Hank. As others have said, they were seen on television with it at least twice towards the end of 1963, playing a live version of Don't Talk To Him. Whether that was a guitar+bass version of a normal 12-string tuning, I don't know, but it was certainly seen on TV around then.
As Stuart said, though, the actual recording of DTTH has been revealed to be double-tracked. My information is that the Burns Double-Six was a nightmare to intonate and this was what caused the double-tracking approach. The production model had a bar-bridge* and Hank's examples seem to have had variations of a couple of different Burns trem-bridges on them in an effort to get some semblance of intonation, even if only on a six-saddle bridge.
It was that 1963 use of the Burns 12 which meant that the 1964 switch to the Marvins seemed, after the initial shock had worn off, to be at least logical.
[* Good intonation on a bar bridge is not out of the question; the Gretsch "Rockin' Bar" bridge has absolutely no adjustment except for height and overall tilt, but the guitars to which it is fitted play perfectly well in tune. Have you ever heard Chet out of tune?]
