eBay item nbr 16132088122i shows a round Gulf Kerosene pump plate. In the in tihe initial description the size is described as 11". The plate does no really look perfectly round. However, when you go to the plate description after opening the site, it decribes the plate at 10.5" and circa 1960. I believe this is a fake pump. Maybe I'm wrong. I would stay away from it.
