My uncle had a B3 with a 147 in his living room. He taught me how to play "Silent Night" on it. Up until then I only played clarinet. I didn't know what I was doing he just showed me which keys to press. Later after taking organ lessons from a "Pop" style of teacher I would go there just to play it and have fun. I still remember "96 Tears" on it. I never hauled a "B3" with the band I played in for 36 years. I did haul an "M3" with 147. I don't miss that at all.
