Default An old dinosaur bench top power supply - help needed

I have had this old bench power supply which I have decided to look into repairing. I have no idea where it came from.

Attached is a picture. I cannot find much information on it to even figure out what it is rated for. The analog display goes to 25V, but the voltage regulator chip is rated for 5V (UA7805 - KC - F 8221 - Korea). The cap is rated a 100uf 50V. There is noting on the bottom but some traces. Pretty much what is seen is what is there.

Any insights into testing? Capability?
