My childhood Organaire

I received this organ as a Christmas gift from my parents when I was around 7 yrs old. I have kept this organ for 50 yrs. Organaire Inc. filed for federal trademark on Dec. 29, 1960 for the Organaire. There are some of these listed on Ebay but I have not found any with as many keys as mine (21 white/15 black/8 major & 8 minor buttons). I believe this to be one of the earlier models. It still plays and is in good condition.
