I have a 1960s moffat built in oven. I have had a replacement element for the base made to pattern of the old elememnt. This was done by a firm I found on the internet, the name and address of which is:-
R.G.PENROSE
LOW STREET
CARLTON
GOOLE
DN14 9PN
TEL:01405869074
tHEY ALSO INDICATE THAT THEY CAN REPAIR OLD COOKERS FROM THAT ERA!!
You may find it helpful to either write to them or give them a ring. If you choose the latter you must be prepared to put a message on their answer phone.
Please let me know if you find this usefull
