This one is as produced in the 1960s-1980s with plain outside dial ring etc.
"Bell On Bell Off" Button can be added for an additional £10
As you can see this is a very nice black 746 produced in the 1970s. It has been stripped down and rebuilt after each part has been cleaned and polished. It is fully tested as working and ready to plug in and go. I will make a dial label with your information at no extra cost.
