I've never seen this type of block. I've spent hours looking online with different search terms and have come up with nothing. The only thing I found was this auction site with "sold" items and with no way to contact the seller:
The blocks have clear P-touch type labels: "AT&T 110TB 1-50" and "95-OH-05 4". I can only assume that the "110TB" stands for Test Block as the center row of brass clips look like they're for testing.
Ultimately, I'd like to find the test clip that goes to these blocks.
