On an Facebook forum we got a question about if this could have any value, and I answered that in some countries it was sold for pretty high bids, more than I could afford. 

Still I PM'd the man and offered $100 and told him that he probably could get far more if he worked a little with the sale, and he answered that I could get it if it was for my selves and not for resale.  ;D ;D ;D ;D

Her it is with some before pictures. (And yes it works!)

Roughly measured REN load at 20Hz 1,1REN but at 25Hz 1,6REN

Congratulations! This was a fair deal, it still pays off to be straightforward with people. Does the phone have a Bakelite shell?

Interesting, you use the dial testing software by K. Pfeffer. I saw a download link in the German forum (https://www.wasser.de/telefon-alt/datenbank/index.pl?kategorie=1000296). It needs a COM port or USB/COM adapter. Might be of interest for others, it seems to work good. I have not tried it myself yet.

The cup the handset rests in smells like bakelite, but the shell it selves looks more like plastic.

I have tried out several different ways to really test dials, the telephone tester used here is the best so far, I only had to buy an USB to com adapter and solder on 2 test wires on a com plug.  The next best is audacity and spreadsheet, works perfect but more of job.  http://www.classicrotaryphones.com/forum/index.php?topic=21454.msg218706#msg218706

I got a message from theseller when I came home. He told me that he bought it at flea market when he was a kid  (1975) and have used it later. His brother discovered the difference between Oslo dial and normal dials, so they glued on new numbering, and then it worket as it should.
Later when he grew up it has been with him but not used for many years.

That looks to be in nice original condition. You did well!
:)

Did not have to do much, cleaning and using a soft cloth with furniture polishing oil on the bakelite. 
Careful oiling and tuning of the dial, (as you see the oil needs time to do its job)
Here are after photos, and tuning data.

What a fun telephone!  Do they make a wall-mount telephone?

According to the test readout, can 11 and 12 pulses be read by a telephone system?
Does 11 represent * and 12 # ?

Thank you
I'd take an educated guess but am unqualified.
In paramediclass, doctor asked me signs of Alzheimers.  "I forget.", I answered.

Lighted Princess® telephones are our favorites!

To ensure an emergent transport call, I need only:
- take first sip of beer when eating pizza
- start shampooing in the shower
- pull bed covers over and get warm and cozy
- begin my OCD oil change.  (Remove oil plug to drain overnight.)

The model 261 got one facelift to 264, which has a polystyrene shell instead of Bakelite. No further drum dial models were made.
A different straight-pull dial existed earlier, and possibly inspired the drum dial. It was for operator desks only, because the mechanism swings out on the underside and is therefore not suitable for normal telephones(see Video below).
dsk's test result shows 10 pulses. 11 and 12 pulse dials were in fact made in small numbers, but for special purposes only, not for general use, and not for dialing # and *.

No wall telephones, and metering pulse no 11 -12 is just to identify errors while measuring.
