Hello David,
It just so happens that I have recently dismantled my old Allen and have saved both of the keyboards in their frames. I also have the pedalboard and bench if anyone is interested in them. I know you prefer something more local, but if you are interested I can take pics and measurements for you. These are from around 1976 I believe.
I originally was going to try and sell the console (see Organ for sale post), however due to time/space limits I needed to get it out of here, so I scrapped the console and kept the keyboards and pedals (with reed switch assembly).
Thus I have 2 61 note manuals with white plastic keys/black sharps and one 32 note AGO pedalboard in a light oak finish as well as a matching bench. They all need to go eventually and I'll soon post them on Ebay if no one is interested in them here in the Hauptwerk community.
Let me know if you have any questions on them.
