That is also my first impression but seeing many such motors in the past the wires condition (especially where they are coming from the plastic cap) makes me believe it is NOS but stored in humid place for some time to get a little surface rust and dirt.It may have a parts sticker but it looks used and not NOS to me.
I think you mean 026 for the former.This will not work on any E9 window. Only E28 rear window motors will work. Bosch last three numbers must be 046 for the Driver's side front or rear and 027 for the passenger's side front or rear.
