Picked up this nice working thermo "Canada Neon-Ray Co. MADE IN USA"
Is there an easy method to open these up to clean the glass lense? There appears to be a very fine seam but not sure if I'm just seeing things or not. If there is no easy or safe way to open, then it will stay the way it is.
I'm interested in Deep Rock and Kerr McGee items especially if they are marked B.A. Tramp Oil
You should join the Pam Clocks and Thermometers group on Facebook, there is a guy on there who can replace glass lenses with supposedly near perfect results. I believe it involves bending the metal edges around the glass back with a popsicle stick. I've replaced glass on Pam style thermometers with this method and had less than perfect results, but better than broken glass. For cleaning, I've dumped a bunch of Windex through the small slit in the back (for Pam thermometers) and it will pool at the bottom and flow through to the front where you can shift it around to somewhat clean. It's hard to tell from the pic whether you just have collected dirt at the bottom or more permanent imperfections, but it won't hurt to try.
John, great clock! It is easy to love the early Canadian GM advertising: thermometers, clocks, signs, etc. with the maple leaf in the background. It just adds a visual interest to what would be a rather boring two letter logo. Cheers, Don.
