Happy Day All...
I rec'd the Bing from Germany today - expensive but expedited,
only a few days to get here.
I cleaned and oiled it and intended trying it on air except...
What appeared to be a valve handle for draining the boiler
is, instead, a black, wooden plug. Bummer. So, I put the air
supply tube into the hole for draining the tank (threads nice
and clean, thankfully), the whistle hissed (sounds like it has
a congestion), and the engine took off. Throttle works, whistle
control works, weighted pressure relief valve works, the sightglass
is sound, and the pressure guage works (Surprise!).
So, I at least need to buy a plug for the drain hole n the boiler.
A proper drain-valve would be best. Does anyone know the
screw/thread dimensions? The filling plug from the top of the
boiler fits there so another one of those would be fine.
Also, the boiler is non-magnetic and appears to be brass but
seems to have a rough patina. The straps appear to be copper
and also appeared tarnished or rough. Is it possible that there
is a coating of lacquer or something else on these parts? And if
so how to clean them up, if at all possible. Also, a photo of the
proper burner would be nice. Anything else.
Finally, but most importantly.....this engine has plastic handles
on the whistle and throttle. Did Bing use plastic handles before
WWII? I'm trying to date this engine but I think it may be one
of those mongrels, making it difficult to date. It was sold as
produced between 1923 and 1933, and I like it a lot, but it does
not look pre-WWII. Plastic handles? I could be wrong.
All ideas are welcome - thankful for all the info already provided,
