Thanks 'catters.
Yes, it is a new guitar that was made by VINTAGE.
The action was a good deal higher than I wanted, when I first saw it in the shop (in Waterford city, Ireland) and, I measured it there. On request, they brought the action down so that it was about 3 or 4 mill lower at the 12th fret. I reckoned then that made it about the same as my old guitar.
I measured it again with a "feeler guage" when I brought it home and it played and sounded comfortable and with a lovely bright tone. I had no opportunity to play it again until last evening when it felt wrong and on measuring it, the strings had returned to near the original height at that 12th fret also. The strings are light guage.
