I would hesitate to mark this 'found'. I think the RES 22 is similar but there are a lot of discrepancies, the front prongs don't look right, the hole on the side is a hole, not a hole and cut-out, there's no writing on the end side and I think the size might be completely different.
When you look at them side by side the differences are clearer:

phillbarron. We are the closest we've ever been to a found item in real life. There are 2 rear posts, nut and bolt, and blade terminals that orient to the side. That's extremely close to the actual prop. Not sure what you meant by "not a hole and cut out". And the writing could have been put by a decal. I not saying its exactly the item used - we are probably off in make and model (its probably a U.K. make). But its definitely the correct Type of device.
Just last week, I was checking car relays and ended up ordering a mini relay just because it had multiple blade terminals. I'd given up home of finding 1 device with all the stuff. We have the correct Type of device found in the real world. We may be off in Make and Model. But just like the "pump widget", the exact make and model is not available anymore - but people have "found" a modern equivalent and made modifications to make it work. I know you are still looking, but I consider this "found".
