[31Cabriolet68-C]

I just went to the seller's additional eBay listings... Impressive!
I've been looking for a motor for my 68C for some time. So I enlarged the picture of the waffle-top details shown on the cover of another gorgeous 31 S/W motor he has listed. Seemed to be exactly right. So I went to the 'Standards' .....
Now comes a bit of a glitch. (But maybe not a deal breaker...)
The top view on eBay indicates a somewhat different pattern/position for the patent-data area, and logo, on the cover than what is shown in the Judging Standards... (Sorry, this can't be too clear. I wish I could post both pics...)
Ok, so my question is: In fine-point judging, looking at a beautiful instrument like this, just how many points (at most!?!) should/could/would be deducted for a variance like that? Would it be the same as if you didn't have any wiper motor at all?
Also, is it known if Trico supplied different- patterned waffle-top parts for later use in
service/replacement? Seems like some of his other motors share this part. Just wondering. Thanks
