V-81 Differences?

[pinballdude]

I don't actively seek machines but I would like to know what others are talking about when the 81s are mentioned.
The listing page for the Vendo 81 mentions version A & B. But I've seen "C" mentioned. Did I see a "D" or am I imagining?
Also there are only 2 versions shown on the listing page but neither mentions if it is "A" or some other version, they just look painted different. I think I've seen an "off center" logo before so that is an "A"? I'd sure like to see photos of all versions under the V-81 listing instead of 2 that look the same. Also, show differences between small/large coin door.
Thanks.

The A came all red with the off centered smaller embossing that is centered to the machine. Both B and D came red with white top, larger embossing that is not centered to the machine but centered to the space above the coin door. Both A and B have the same size smaller coin door while the D has the larger coin door. I'm not sure if the C has ever been confirmed but if so it is just like a D but all red.

If you google it there are pictures of an 81 C that I have come across in the past. Shows the data plate and everything.

The C is  Vendo Factory  verified, just not many  produced.
