As more and more Ericofons go through my hands there are more specials I come across. The chassis below I want to share with you. It is part of a Swedish made Old Case. The chassis is original, it was not tweaked by someone, that would be visible.

The contacts on this K2 chassis from 1958 are of a specific type. Never seen these before. Also the microphone is special to fit the contacts. Maybe this is a custom made chassis… If anyone has a clue on this one, please let me know.
