Lumley Amps

I have a pair of Raymond Lumley monoblock tubed amps. These are rated at 150 watts per amp. I am beginning to think I have the only pair in the U.S. Does anyone who reads this have knowledge of any other Lumleys out there? Mine are a Signature model. Thanks in advance.
I have Ray Lumley amps. Mono block. M-100. Bought in 1982 or 1983 directly from Ray's shop in Denmead, UK.
How do you like yours?
I believe Ray sold the business a few years ago.
