It is the 774 which is by far the rarer of the two. 874 adapters are easy to come by. Pasternack Enterprises stocks quite a selection of them new, but Pasternack is expensive. Although 874 adapters are not as common at swap meets as they were 20 years ago I do sometimes see them, and I prefer used GR adapters to the newer production that Pasternack stocks. I have a good-sized tackle box that over the decades I have filled with used and NOS 874 adapters, connectors, cables, and accessories such as mixer Ts, straight Ts, elbows, adjustable lines, terminations, and filters. I still use them for my work as a broadcast engineer.

If you are looking for 874 adapters etc. try eBay - there are generally a few hundred of them there at any given time.

As I noted upstream you can roll your own 774 connectors and adapters. GR 900 series adapters (the successor to the 874 series) are harder to find and more expensive than 874 adapters, but there are always some 900 series items on eBay. I don't recall seeing any 774 series on eBay.
