Over the years, I have had many Electro-Chemical Engraving openers and openers with corkscrews.
In the JFO-world, these are known as M-3s or M-73s.
M-3 – opener only
M-73 – opener and corkscrew
And, as one would surmise there are lots of variations out there with various advertisements.
Don Bull has tons of information on his website on the Electro-Chemical Engraving co, and their wares, and you can link to his Electro-Chemical Engraving page here:
And, on that page, you will find an image of three different Electro-Chemical Engraving advertising pieces, advertising the Electro-Chemical Engraving Co; the M-3 and there are two different sizes of the M-73.
I would love to add a couple of these to the collection.
While I have had a wide array of various M-73s over the years, the longer Electro-Chemical Engraving Co., corkscrew has proven illusive (although RL has two of them).
If you do have an Electro-Chemical Engraving Co. M-3 OR M-73 in either size…
I am always up for a trade! Drop me a line!
