1 DCBirdMan 4 weeks ago Well I pulled together pix of the Atkins double cut Gent12 and the single cut Harrison Tenny style 12. Both were black, both had Supertrons, single cut had a black guard but could have been replaced in the last 50+ years. Both have same righteous wide neck. Headstock plates look different. Anything else observed by experts?? We know that serial # of the Atkins model was 61852... so that's pre mid '66 serial # changeover? The album was released March '66 so this would seem correct. My theory is that George was so used to the narrow neck Rick 12 that the wide neck was not to his liking. So as he did with many of his guitars, he gave it away.
