Does anyone have / can anyone link a comparison of the various repro holograms over the years? I picked one up (working on fixing up a machine for sale in a few weeks) but have NO information on it as to source. It doesn't look_ like any of the recent repros, the upper lip on all them looked smaller / thinner than the this, but this doesn't have any blue or red tinting to it so I'm not sure. It's adhesive backed, to stick to the metal plate I presume? I attached a pic, it's REALLY hard to get a clear pic.
