Who stocks parts for older Verine gas fires?

I have a 20 year old Verine 'Zephyr' gas fire (coal effect). It requires a new pilot injector unit (NOT an oxypilot, this doesn't fit). The current pilot burner goes out after a few minutes, even after it has been cleaned by a gas fitter.

Can anyone inform me of a stockist who carries spare parts for older fires? The manufacturer cannot help.
thank you.
