Here is a picture (apology to e* seller for my stealing the auction photo!) of a No Embossing signal. It has a Pennycuick drip in the top of the pinhole, and sharp well done threads. It is dark aqua (much darker than photo) and crude with lots of bubbles, swirls and such. The WG is thicker than most other 164's I own like Maydwell, KCGW, and Hemi 20's. Any idea what I have here? Thanks all!
