How does it compare to a Bertie Allan ? still not much about the Stirling on the internet and Mamod have been quiet about it recently on their Facebook page no full reviews yet, thanks.
It's not quite as refined as a Bertie perhaps but it has a pressure gauge and a filler valve so you can fill the boiler while in steam. It is certainly just as well made as the Bertie and has a very controllable slow speed. I'll try and do a comparative review with Bertie if my arthritis stops playing me up......Allan.
