The TVR1 is NOT made nor sold by Miniature Steam Pty Ltd. (There are a variety of TVR model numbers but we believe they all have the same external dimensions and connecting points for steam input and exhaust. Accordingly we believe we do not need to differentiate the models and use TVR1 in the collective sense.)
It is a very successful engine made by Graham Industries in the USA and has attracted a very large, world wide, market. To our knowledge Graham Industries do not provide a matching boiler for their engine.
We are making steam plants that the owners of TVR1 engines can not only run their engines under steam but also fit them into RC controlled boats.
