I could not resist to buy another seen on facebook, The dial was looking different, and it turned out to be 1946 Siemens Olap from Milano Italy.   Learning about this the modell 36 phones was made post war of what they had, and the digrams varies according to that. I made a diagram and based it on a W28 just to show the difference.  Mainly the dial is the difference between my first and this one.

Dial speed originally, and now, no cleaning/oiling or adjustments done:

Nice! Was the above test slip folded inside the telephone from the original quality management?
The N38 dial was Siemens's first one with a fast running governor, which anybody else used long since. The N24 and N30 dials had the pulsing mechanism right on the governor shaft and are more tricky to adjust. The N38 is quite bullet proof. It was also the first Siemens dial making 2 extra pulses, which then are suppressed by the nsr contact. The Post wanted this to allow a little more time between dialing each digit, for the selectors to work correctly in the office. Hence the longer travel between the 1 and the fingerstop.

Thanks for the clearly drawn diagram of the Modell 36, the few that could be found on the internet are more confusing than helpful. Likewise the glued in sticker is more a wire routing scheme than a real diagram.

Thank you for that info, I just guessed about the wish for longer period between the digits.

Agree!  Other versions of the modell 36 may have different dial wiring. (as my first on top here).
