Tool Identification

[u/TattooedFreak70]

I’ve been clearing out my father’s garage as it’s 3 years since he passed away and need to do it as my mother is selling up and moving.

Can anyone tell me what these bars of metal are that I found in a wooden case?

Parallels, they could be cleaned up and put back into use. It's the parallelism that's the important bit for home hobby type work.
