Hi Keith/Hank, I've really enjoyed the postings and reminiscences of you (and all the others) on this and the other current LD thread- you certainly know your stuff and obviously love the music. I may be wrong about the 12-string, but I know for sure Stan Francis made one for Pete Seeger's, and that that one imploded (so did Lonnie's), so I shall not be moved (yet). Pete S. had a copy made by Bruce Taylor(USA) when his Stan Francis one gave up the ghost. Very interesting indeed about the Abbotts, there can't have been that many made, so there'll be hardly any left, wonder where Lonnie's is now! I too have played one of Lonnie's guitars (00028)- (I didn't attempt Rock Island Line though!) The action was highish and the strings he used were quite heavy, it was not easy to play- his fingers must have been sore after a long concert given his hard strumming style. Many's the time I've pestered staff in Hank's, maybe we've met! According to Roger R earlier the mahogany Martin was an "0" size by the way.
