ACTUALLY, it was a Hammond M3 which was cut down and put into a Vox Continental Organ - looking black tolexed box for Merrilee (Rush) and The Turnabouts - Seattle circa 1966-70. Don't remember if there was a Sunn logo on it or just plain. Not too many other N.W. keyboardists used one - if any. Most lugged the M3(Dynamics/Springfield Rifle) - I think Don Galluci( Don & The Goodtimes) used the B3. The M3 was cheaper & lighter to move and sounded much fuller than the Vox and most played sitting down( B3) if standing(M3).Some guys cut off the bottom of B3's - the phrase ' chopped Hammond ' became common. Sunn supplied the backline at the Teenage Spectaculars staged every summer at the old Seattle Coliseum - there probably was one there though I have a photo of The Springfield Rifle performing in front of a Sunn backline( they owned & played Fender Dual Showmans) but Terry Afdem is seen playing a Vox . I'd have to check my Sunn catalogs to see if they actually listed it.
