Triang R160 hand uncoupler tool

[Evostar90]

Not sure it this is the wight place for this question but as it's a tool question
I have seen a few people on YouTube use the triang hand uncoupler tool and i managed to get one from eBay recently i was just wondering when they were first introduced and when they stoped putting them in sets
Thanks Lorraine

I don't remember them being in sets. I just remember we suddenly had one.
