Hmmm... any chance for a picture?
We built a number of Heathkits including the Paramount model organ. The Paramount is a theatre style spinet with the Thomas style extended natural spinet pedals, not the 25 note Celebrity style. As far as I can remember there were just two styles of Thomas by Heathkit organs, the Paramount and a smaller Malibu-like spinet. There were also some combo organs but I can't remember ever seeing a full console version. I believe that the Thomas by Heathkit versions were essentially identical to the corresponding factory built Thomas organs.
