Sentry Fireproof Cash Box Unlocking

"It's an old safe, but I want you to open it."

It is said to be a cylinder-type cash box that can be opened with a key.Is it made by Sentry?

When I confirmed it on site, it was a Sentry-made hand-held fireproof safe. Since it was a 4-pin cylinder, it was usually completed by picking and unlocking.

The cylinder was full of dust, and when I checked the inside, it was empty.He recommended disposing of it with oversized trash.
