Hard to say for sure from the picture. What does the back look like? His feedback on eBay has a lot of Sinclair stuff, maybe he ran into a stash of NOS stuff. It still happens. The logo on the plate came out in 1959, not all signs were being made from as heavy metal and the porcelain shelving was getting thinner by that time. I do not know who is selling the stuff but it could be real stuff. On a side note, a very nice original Dino pump plate normally sells for around $100 - 125. You paid more but if it is real I would say hang it up on the wall and enjoy it
