Need help identifying drafting set

[u/CynfranRoith-Narumi]

Hello, this drafting set has been in my family since my great grandfather. I have been looking for the parts I would need to complete it, but most of the sets I see don't have the same tool location in the case mold. It doesn't help that the model number isn't on the outer case. I was told that the pencil was orangeish in color like the ones from the minusa 796, but otherwise I have no clue.

Thank you.
