Ok. I couldn’t let it rest. Your comment made me think of another way of doing this, along with @jamesdhatch’s suggestion.
I put masking over the original reflector, trimmed it around the edges and placed it in the bed over a dark background. I realized I just needed the contrast here.
This didn’t quite make it all the way around to be able to differentiate a cut. The bottom is pretty precise and detailed. The shadows in the cutouts interfere with a good scan.
This one work out that I could get a complete outline and delete what I didn’t want.
This will work out.
This is the cut file placed around the original image.
This is original overlaid on the copy. Is pretty close. The reproduced part is slightly larger and the holes for the screws are just a little small. A rat tail file would clean it up enough to fit perfectly.
I’d call this a success. I think if I had used a whiter masking and elminated the shadows around the bottom mount holes, we’d have a replica without needing any post processing.
Thanks for the input everyone.
