http://jedistar.com/noble-guitars/ - was the one you were looking at mentioning they were imported by Strum and Drum / Ron / Don Noble? It could have been a store special for Strum and Drum.
Nope, found info on http://www.myrareguitars.com/vintage-1968-noble-eg-686-2ht-electric-guitar.
Does Strum & Drum even exist anymore, maybe under a different name? Could well be a S&D store special but a bit odd as we know the Noble name was used up to 1970 but, according to its serial number, this Les Paul is from 1977. Given that it was actually purchased in early 1978, that serial number makes sense. However, seems odd that they would suddenly re-use that name for a one-off batch, unless it maybe had some significance for them.
EDIT: Just found this site: https://www.guitarforums.com/showthread.php?t=45956
According to the OP, Noble was manufactured by Kawai/Teisco. Anything to do with Matsumoku?
