It looks exactly like the Dialog (manufactured by Ericsson, or probably L. M. Ericsson at the time) that were ubiquitous in Sweden in the 70s and 80s: https://en.wikipedia.org/wiki/Ericsson_Dialog .

Definitely not Swedish. While the design might be, the pulse coding was different than nearly anywhere else. In Sweden zero was first, usually it's last. https://sv.m.wikipedia.org/wiki/Telefon#/media/Fil%3ADialog_...

In some country I have seen reverse coding, i.e. increasing number dialled gave decreasing number of pulses. Maybe Norway???

Big endian vs. little endian is not something new that came with digital computers :)

Edit: Only Oslo (different from the rest of Norway) and New Zealand had the inverted coding.
