I found it in late 1979 or early 1980; I was turned on to it by Tom Verlaine, of course, and was working in a guitar shop where I kept a 77 or 78 brochure, with a Daphne Blue JM on the cover. I'd seen Elvis C using one in Leeds in 77 (covered in gob), and (a young skinny, crop-haired) Robert Smith playing an Olympic White one in Hull, summer of 79. The area sales director for Ohm amps found me one in Manchester, which he said had been butchered, but resprayed by Gordon Smith. June 1963. £180. When it arrived I was overjoyed; apart from anything, it played beautifully, that characteristic chiming sound, and once set up, perfect intonation, the most in-tune guitar I've ever owned (alongside my Tele, which I got in 1991).
I used this on every record my band made; it never let me down live, always stayed in perfect tune. You can hear it here

Here is it in action. Please excuse the mullet. I think this show was in Gary Numan's home town, or orgaised by his fan club, the audience was entirely Gary Numan clones.

One time after the last song, I threw it face down and it stayed slowly bouncing up and down on the trem, feeding back, the most awesome sound ever. When we came back for the encore it was still in perfect tune. I've had numerous offers to buy it, including from Robin Guthrie (who I don't think owned a JM before trying mine). Since acquiring it, I occasionally used a Gretsch 6120 (better Feedback) and a much later a blackguard Tele> BUt this has remained my key guitar.
After our last record company, Red Rhino, went bust I moved into working for magazines, and my JM helped me walk into my first job. I told the editor at International Musician that vintage was A Thing. My audition piece was on affordable classics, which featured my guitar. SO It helped get me the job I've had pretty much ever since. Which has always been heavily JM-slanted. Ive seen quite a few J Mascis, MBV and maybe Sonic Youth pics on here that I commissioned for the guitar mag I went onto... any band with a JM always got good consideration.

And here's how it looked from 1979 to the summer of 2018.

And the headstock. Didn't know that much about why somebody would do this until I found this site.
