We talked about this awhile back under the general forum. I got a repro just to compare side by side. The real pump plate is on the right and the fake on the left. Pictures tell it all. Ted
This was also added by an old gas member.
Here are the real facts on the 9 3/4" Tydol pump plates...
1) Both the Tydol Flying A (green) and the Tydol Ethyl (red) pump signs have been reproduced in the exact 9 3/4" diameter as the originals. These repop signs have been sold regularly on eBay for a year or two, usually for $20-$25.
2) The repops have white backs and the mounting holes are further from the edge, directly over the black trim line.
3) Genuine Tydol pump plates have mounting holes closer to the edge, barely touching the black trim line. The backs are generally light green but NEVER white.
4) Tydol pump signs with three mounting holes are genuine but much scarcer than the four hole signs.
Hope this info helps other collectors from getting burned in the future.
