69 Bowtie question

[Rufcar]

Today I found this in one of my boxes. I removed it from my 69 Camaro in early 1970 as I wanted to paint my grill flat black with no Bowtie. I notice on all the ones for sale they all show the backer plate in raw zinc plating. This is a factory original and the back has a factory flat black finish on it and I know mine is correct as I removed it from the car myself back then and has remained in a box ever since.
That all said, what do you guys think? I also notice my 2 part numbers are 3949705 and the assy # is 3943219 and I see supposedly NOS bowties on ebay in the boxes and they do not have this number?

Backing plate looks like the one I have in a misc box of parts in the back garage so I would say it is assembly line.  Took mine off an LM1 automatic car I parted out in the late 70's.  THM350 and 12 bolt that ran and drove.  It was junk as it needed rear quarters.  I know... I have nightmares over that lapse of judgement.

Mike don't feel bad I traded mine in 73 for a limited edition Millionth Orange Vega!  jim

The separate retainer plate for my all-original 02D '69 Z/28 emblem has never been touched, and it was originally painted black primer.

Thanks John as I agree with you as mine is also black Primer which tells all of us that most all the ones for sale have the wrong zinc back plates. Then again one could always paint the zinc flat black!  Tkx again. Jim
