This was purchased for use on my 70 P project. Project is no more, so this is up for sale. It doesn't have the long G screw, so I guess it could be before 70-73 or after. Since the seller sold it to me as a 75, that's what I will call it. Looks great, and has the patina you are looking for to match that era.
Comes with screws.
