I don't know what they look like but if they just glass etched I might be able to help you out. If you have a pic I can tell ya more. I have the ability to cut things out of a blast guard with my plotter, then I just hit it with the sand blaster.... Not sure if that's what your looking for , but I figured I would offer.

Original without etching?
Thank you very much for your help in this! IŽll check the link and we will see what comes out of it.
Thanks again

The original bottles are not etched. This gives you the competitive advantage of bringing more of your favorite liquor and filling two or three bottles with it.

Seriously though, the ones on eBay look dimensionally the same as from the factory and the pump mechanisms are identical as well.
