All TouchTone chassis for the North Electric 60A were made in Sweden by LM Ericsson.
They shipped the chassis to the USA where they were fitted with shells from the usual
color pallet of eight colors.
LME also put out some TouchTone Ericofons for use in Sweden and possibly other countries. These LM Ericsson TouchTones are very hard to find. They came in ivory, red, green, gray, blue, and Sandalwood.
