How old and what time of suspender parts are these.

[TNBBNAYLOR]

I found these at 2 different house. I think The big one is a adjuster but I'm not sure about the small one. I think the small one is for kid while the big one is for an adult. If you know please tell me what part of the of the suspender these would have been for and how old they might be.

When I said "time" in the title I meant type. And the dime is comparison
