M&S Systems Musical Intercom Mc350A White. This is an estate find. Guy was a contractor. It is still in the box but is untested. Instructions are included. Does not include anything for mounting it. You get box, instructions, and unit pictured. If there was anything else that went with it it is not included. I see no damage to it anywhere and think it should work. The fuses are not blown in it. What i am assuming happened is the contractor went to build a development and bought in bulk but technology or persons taste changed before the install. Since I have nothing to test it with it is sold as is.
