I had posted the below comment under Bob's thread on Associated Air signs, but for those that may skip a topic because the brand discussed isn't their brand I am posting this under a Mobil heading as well.
"You can add the Mobiloil plates to the list now too....Dan and I discussed them today. eBay item 262482969256. This curved one is also a repro, item 222153608855.
In my 10+ years specializing in Mobil, I have never seen an original Mobiloil plate dated any year but IR46.
Unbelievable....I was just on eBay to get another item number and yet ANOTHER shows up with the IR40 date, eBay item 262487238869!
I looked at their other items and this Mobilfuel is fake too...eBay item 262487234676.
I just can't believe it anymore guys, I'm almost speechless right now. Four new Mobil repros in the last 2 months! Metro, restroom, Mobiloil, and "thin border" Mobilfuel, even though the border is too thick on the repro.
