Any way to open a Patchbay and tell if its balanced/unbalanced? Signal Flex PB-32

Hey guys,

So, i picked up a used rack case and threw in an old Signal Flex PB-32 Patch Box Patchbay for $10, figuring it could be useful. The problem is, the little information I'm finding about it has conflicting information regarding whether the connections are TS or TRS.

One Reverb listing I'm seeing says TS, while another old post on another forum claims TRS.

So my question is, is there anyway if I open this I'd be able to tell from the jacks if they're TS or TRS? I could post pictures if that would be helpful.
