Roger: there was another 00028 in the picture, one I saw Lonnie use sometimes and pictured on the cover of "Sundown" with an oversize pickguard. He also claimed to have given one away to a Manchester United player- quite possibly a myth. There's his first ever guitar- a classical- and a Gretsch electric he imported in the 50's but probably never used in his act, which I referred to earlier somewhere. Then the Francis (or maybe Bailey) (see above) 12-string, the Guild 12, the aforementioned Abbott, and of course the 017 and the Martin LD personal (sunburst) guitars as you mentioned. I'm not sure whether this sheds any light- perhaps sheds more dark!
