Instructokeyer Manual/schematic?
 

Hi,
I am looking for a Manual(a schematic would be nice as well but isn't
necessary) for a Instructokeyer Model- IK-440

It was built by Curtis Electro Devices,Inc.
In Mountain View California

Does anybody know of a place online that one can be downloaded from or
maybe somebody could scan and email to me?

Any help with this would be greatly appreciated.
Thank you
