Burroughs vintage adding machine portable register

Description

Please check the photos. I believe we have this in my parents' attic because back in the 60s and 70s, my uncle worked fixing adding machines, cash registers, and the like. I really don't know a lot about it.
If you have questions, I can likely be of most help with things like appearance. All others questions, feel free to ask and I will do my best to get the answers.
Thank you so much for your interest. :)
