Hi,i always thought the D hole twelve string was made by John Bailey,who at that time made for, and repaired for the folky lot,including Pete Seeger,Jimmie Magreggor,John Reinbourne,etc,John Bailey certainly made the same model,it always looked a a bit homemade,but it had a fantastic sound,i aquired Lonnies Abbott when i owned Hanks Guiar Shop,i offered it back to Lonnie,but he did not want to pay i beleive the £750 price.that Abbott guitar was made in 1928 at a cost of £15gns.i still own one today,and have the original catalogue....Lonnie also used in the early days a Martin 00021,this guitar he told me he gave to Adam Faith,who smashed it up in his car accident,i think he used the 00021 up to around 1962/3 and in the early fifties i saw him with the all mahogany Martin 0017....
