That has two legs connected to a body. Theirs has the two legs connected to each other and doesn’t have a body. It’s a bit nitpicky to call that really different, though. The axle connecting the two legs can be considered a very much shrunken body. I also suspect that, just like this one, that ancient toy has only one actuator.
