This is a classic mid-century bakelite telephone in highly desirable ivory bakelite.It has been converted to slot into a modern connection but it is currently untested. I no longer have a phone line but my friend has and I will test it there if it's a sticking point. The model number is 312L and dates to the 1950s. The handset flex is a very light brown (taupe, camel or greige) which complements the ivory for a very sophisticated look. The connecting wire to the wall socket is an ivory colour.
