Derrick,
I have a new, never used, big metal Keystone overhead projector, still in the box. If interested, email me at billmccoskey@aol.com.
Hello Bill,
Thanks for the offer. I really don’t collect any of Keystone’s cameras or projectors. I have a few that someone gave me and ephemera. That is really it.
Derrick
