Charlie - this is a very nice display - but it is incomplete
there are still many more models from Stuart available....
Arnold
Yes there are Arnold! 
I have a Score somewhere. Don’t remember what I did with it. Here is a video of it running with my DaVinci Drum Model and Water Pump.
A Stuart Victoria is definitely on the list; as is the Stuart Pump Jack; and the Stuart Air Hammer.
I also had a very small Stuart one-one or No. 11 which went to Gil as a gift and I never was able to get it working. I don’t believe he has ever gotten it to run either. It was a very early version and had a tag that said:
Stuart Turner Ltd.
Makers
Henley on Thames
I had a Stuart No.1 which I sold to Saint Paul Steam. The No. 1 came from Italy and was purchased in the 1980s from the Steam Age Shop in London. Bruce is now the third owner.
Hello Charlie - the Nr. 1 is in my opinion very beautiful and strong but best looking and working
is the Twin Victoria. My Favorit was always the Major Beam - fabulous engine. There are so many
nice ones - haha
The steam hammer also is a great one and fun to run.
Have you seen my Score with reverse?
