Maybe it was once clockwork and somebody has modified it so that it is now rubber driven. As it is, it is certainly not a production item though whoever did it did a competent job and it appears to work well. However I have never installed it in a model.
Sorry I thought they were different escapements and the the top one looks awfully like an ED clockwork escapement, but it's possible that ED did a rubber driven escapement I don't know about, hopefully somebody else can tell us. Or as you say, somebody could have modified and ED escapement.
