Supamix mechanical hot & cold mixing valve

My father has a shower fitted with a supamix mechanical hot & cold mixing valve from FH Bourner & Co. who I believe have gone into liquidation. The shower is leaking and the problem is the O-ring. He has tried three different ones but none of them quite fit. Are you able to supply a suitable O-ring please? Many thanks.

I am afraid we don’t have the correct ‘O’ ring all I can suggest is buying a pack of assorted ‘O’ rings from say B&Q and trying to go through them until you find one that fits.
