Was given these 2 at work today, my first buckling spring boards!

Luckily they look to be in like new condition, they were wrapped in new/old bubble wrap, and the cable on the bigger one looks to have never been used.
But I was having trouble identifying the first one. The sticker covering the original has a model number but it doesn't seem to be correct when looking. I can find a lot of similar boards but nothing quite close enough. Any help fam? It's probably something well known that i'm not keen enough to locate haha.
Also they have rj45 connectors, since they were old terminal keyboards so I'm not even sure they're usable.
