@lindemann06 Hi Rob, thanks for the photos and I love the last one, they tend to photo better on a cold day when you can see the steam exhaust. Your ceramic fibre paper insulation gasket is available also on Amazon, just thought I would mention that in passing. Saito make some really nicely engineered steam engines and the T2DR IS a well proven model. I checked out your Hercules Steam Tug, to find the asking price is £625.00, that is a serious amount of cash. That is one seriously expensive boat you have there. Regards, Gary. (Just a passing thought that I will stick to my butane propane gas canisters, and I always fit a gas cut off valve, I once got caught short and ran out of water, I will never forget the awful smell of cremated hard wood strips around the boiler.)
