Three Dimension Company case, Slide racks, metal 2x2 Slide mounts, Slide Glass

Description

This does not include film or the projector for these itself, this sale includes Three Dimension Company case, Slide racks, metal 2x2 Slide mounts, Optically Clear Slide Glass. There is minor wear on the case, nothing bad for how old it is. There are 2 packages of 40 optical glass squares, they have not been touched by me and are closed tight so I dont believe they have been touched. 3 packs of 20 pairs of metal slide mounts for 2x2 slides, and 8 slide racks, one slide rack without its box.
Boxes are in wonderful condition.
I estimate this to be from around 1957, the TDC was in operation from 1940-1980, from my research on the objects in this case I estimate 1954-1957.
The case has minor dings on it, does not smell like it was from a smokers home, smells like it was from a library. Clasp still works and it has its original plastic/rubber feet on it. Doesnt look like it was remanufactured in any way, original clasps, handle, hinges. One minor dent in the bottom of the case.
This item was purchased in Omaha NE, USA, but would love to get it to someone who collects slide projectors or slide projector accessories, it would be a good addition to theirs.
Can negotiate price, but send reasonable offers, this is an antique package, and vintage in style. There is no other listing on eBay even close to what my package has in it. If you request more pictures, I will send whatever you need to help verify products!
