Hello John! Good to hear from you. On the Student Butterfly and the Square Spinet "64" I need any thing about how many were built, why there were built, who designed them, production dates ect. I have one Butterfly ser. # 226880 and two Sp. "64" both of these have 8-23-45 stamped on the keys. These will be on display at the PTG Foundation exibit in the convention hotel in July. There will also be several outher full sized Pianos. I am forming this list now and will post it on the list when completed. Hope to see you there. Thanks, Jack Wyatt
