James, I've found alot of description errors in Ebay listings. Most sales are by people who know almost nothing about the organ or its history. I find Wurly numbers a little confusing to start with as my console is a 4735 and my spinet is a 4375. So it is easy for people to get crossed up on numbers when speaking of the Wurly's.
I'll be interested to see any further information on this model number. I'm considering an older 70's church model that I see listed on Ebay and You Tube sometimes and I have a hard time keeping track of that model # as well.
Cost of getting old I guess? Check out video http://www.youtube.com/watch?v=XayWt...eature=related It is on the order of what my friend has and the tone isn't as nice as the 4735 which later became the Centura Professional.
