These are now becoming a very rare item as often get broken when the machine gets a bash or falls over, sometimes they have the Teac brand name on sometimes not, I am guessing they were a later generic replacement by the original manufacturer of these tables.
Some mild corrosion is common on these units and need to be buffed up
Its getting to the point where i may have to have the centre tridents made, one style is just screwed into a moulding and fixed , another it could be changed by taking off a circlip a third thats used on machines that do not have flat backs is just screwed in
I was qouted 10 pounds each for the central bit and needed to order 2-300 at that rate
so its a chunk of change
