In regard to John Tuttle's search for an Aeolian player pump,
I may be able to help out.  I might have one in my shop that is
complete.  I pulled it out of a Duo-Art Console a couple of years
ago.  The pump seems alright but that piano needed more power
because of the stupid valve system.  I will contact you in the
near future; let me dig it out if it's still there.
