Quote from: TelePlay on July 17, 2022, 01:03:48 PMI don't have a clue of what that has to do with this dial in this topic but a prior reply is interesting in that it shows how the governor is tucked away with the main gear (missing in the image) meshes with the worm gear on the governor and somehow the main spring gear around the main spring shaft. It almost seems the main meshes face to face instead of edge to edge to convert spring torque 90 degrees from vertical to the horizontal main gear (not shown but the axle point and depression for the main gear is seen in the image).There is a lot more intricate engineering to this dial, more complex, than most. At least there is access to the governor so that the fly wings can be worked on to adjust dial speed.A chronological photo display showing step by step how the dial is disassembled would be interesting and helpful. Granted, there aren't a whole lot of these out there and most people won't attempt disassembly but for the knowledge base, it would be interesting to see how this dial is made and functions.All dials aren't that complicated in that the telephone manufacturers hired people off the street to put them together. The engineers designed the dials but also designed them to be assembled by a common man off the street, not rocket science. Problem is that some dials, when assembled, were done so in a way that does not allow them to be taken apart - some SC dials have the number plate fixed to the dial housing by bending over metal prongs. This dial may have that issue as well in some of its parts, say the governor which from the picture looks like it's permanently attached to the dial case.

Quote from: tubaman on July 17, 2022, 04:29:35 PMIt slides open, but even on my NOS one it's pretty stiff.
Quote from: tubaman on July 17, 2022, 08:09:25 AMThese are certainly interesting dials. I have this NOS one I picked-up some years ago. The governor door is stamped "5 31" - May 1931?All I need now is a phone to go with it.
QuoteOkay, North Electric, . . .
Quote from: kleenax on July 17, 2022, 06:23:58 PMYour NOS North Dial is the smaller version, I believe 2-7/8" instead of the larger 3" dial. Your dial was used primarily on Stromberg-Carlson Dial sticks, but is found on some other phones. Needs an adapter plate to mount however.
