Ive got a 30 year old Vulcan continental boiler ?

Can you tell me where I can get a thermostat for a 30 year old Vulcan continental boiler? I live in the Liverpool area. Any ideas, could you let me know.
All I can see on the boiler, as follows
SMG, 240v, 1PH, 50Hz, 05603A 130-70W, Commodore 130. On the lowest setting the water reaches boiling point.


Thankyou
