STAR TREK: ENT “SICKBAY GURNEY LOT"
There are a lot of scoop stretchers that look similar to this, but the exact details and metal finish is particular to this example.
This appears to be one of those things that get sold under multiple brand names. I found several look-alikes with different names like Ferno and Junkin.
There’s a couple on eBay now; the first is a reasonable price, if anyone wants one.
