1958-1973 Ford FE Ignition Coil, Black with Mustard Yellow Top

Description

For sale is what looks to be a brand mustard top ignition coil
. Correct for most 1956-1973 Ford and Mercury FE applications.
Part number: B6A-12029-B ??
only markings on it is 12v stamped on the bottom. I bought this part back in 1989 (I have the reciept)  I have no idea if it's NOS or repro ?
reciept states 1956-57 12V coil.
this is a darker mustard colored top which leads me to believe it's a ford original but a very early part. I see repro's out there the top is a much brighter yellow.
Just my opinion. I bought this 30 years ago has been in my parts pile all boxed and wrapped safe and secure.
