the sets all include the star, however they do not have the double arrow for in between the the "18" and the serial number. they have just a straight "dash' stamp instead. however, when i look thru my hoard of junk i see that not all trans numbers are the same pattern. some have the double arrow, some have a dash, and some just have a wide blank space. all old junk, hard to imagine someone messed with them, so my guess is that its another "what ever the guy on the line felt like doing", or a difference in manufacturing plants
