I started with this which i won on TradeMe
It is a early David Auld
after a little bit of cleaning and a new base
note we still have no safety valve cap
all we needed was a solid pieces of brass turned and drill
then apiece of rubber inside the hole to seal against the thin shaft you can see on top of the boiler

Looks a lot better now Dennis. A competent runner too! What date are we looking at with regard to its manufacture. I assume these are quite rare, I knew of the mobiles but not the stationaries.

according to what we can find out he started about 1966 and went until 1988/89 we think his early ones were copper boiler then he progressed to brass. the safety valve is a dangerous affair if held down and twisted it seems to lock onto the rubber insert and when engine in full steam if you tap the valve it leaps about 2 feet into the air

Nice restoration Dennis, and a nice runner too.
Where does the steam pipe enter the boiler? Does it run up inside a la Bowman?
Spokesmann
You've tried that then!
Scorpion2nz
steam pipe enters boiler at 1 end (nearest burner tank) from underneath then runs along underneath boiler to other end so is super heated . then up and over firebox.
As for reference to bowman I don't know as don't have one.
and as for safety valve/cap how do you think i know

Charming little engine, scrubbed up well too
What sort of numbers were these produced in?
Scorpion2nz
numbers well no idea hard to find information but I only know of 1 other

Ohh that is nice, you've done a fine job there Den

I see now - thanks. It's similar to Mamod's Idea of taking the steam pipe through the burner flame, but much neater the Mamod I'd say.
(Bowmans have the steam pipe starting inside the dome and emerging through the boiler at either the base or side - no 'superheating'.)
