Thanks for the comments. I'm not so much looking for valuation per se, just was curious for information as why some variations are worth little while others are worth much more. And I suppose I was hoping for a shortcut to the info, what's the difference between all these variations, the rims, the dots, etc.. Yes, there are dozens of threads and I skimmed a few but thought perhaps some kind soul would point me in the right direction rather than spending several hours reading.
I'm not a collector, and don't get too much caught up in the minutiae of equipment, generally speaking. I just like stuff that works well for the purpose I intend it.
So based on what I have read and a couple of PM's, mine is dated between 1945 -48, and is coated. Feel free to chime in with more if you wish. And if you were annoyed by the request feel free to ignore and move on with your day.
Cheers
