info on majestic series 1122

Hello all,
New member here, very ignorant of early tv and grateful for any help. I've recently acquired a majestic series 1122. It is in great shape. It seems to work but I haven't attached an antenna so just get snow. Does anyone have any idea what it could be worth? I've attached a couple of pics. Any help is much appreciated. I don't know what I would have done if I hadn't found this site!
