1965. John, Mark and Mike. Me playing my first guitar at 14 or 15. This was a Harmony Stella, model #H-929. After that I got a Yamaha, and then bought Bill's Martin D-28 from him for $350 when he needed cash to go hitchhiking around the country.

For the guitar history buffs out there, here is the Harmony Guitar catalog from 1965. Thanks to vintageguitarandbass.com for access to this catalog.
