Glow plug needs a battery only until engine starts, then it is self

True about the glow plug engines--marvelously ingenious little gadgets.
I (wrongly) assumed that the wire would be removed once the engine was

It's a conventional spark-ignition engine. Through the '40s, at least, most
larger model engines had spark ignition.
I'm no expert, but I believe at least some (indeed generally larger)
model engines still use spark ignition. Small airplanes these days
often use electric motors, presumably made practical by advances in
battery technology (Li-ion cells that have a quite large power density
and can withstand pretty rapid discharge rates).

1775 could be a jack for burying drain pipe...
Nope, it's not for drain pipe, no one has guessed correctly yet for this
device.
Rob
It appears made to lift a wheel or shaft from ground level to 5" or at
the highest setting, from 6" to 11". It looks good for 300 pounds.
The ring looks big enough to hold the metal band around the hub of a
wooden wagon wheel. In the days of wooden wheels, I imagine wheels
often sunk too deep for a horse to pull, sinking while underway or while
the vehicle was parked. Wheels could also get stuck between rocks.
This could be a tool for a farmer to lift a wheel enough to put gravel
under it and free the vehicle. Before lifting, I would want to chain
the ring to the spokes so it wouldn't slip off. The studs may have had
something to do with a mechanism to hold the jack on the wheel.
If the wheel needed to be raised to ground level, the jack would be
limited to wheels of 30" or less. If the farmer had a stable support
for the jack, it could work for taller wheels. |

It looks as if it might have a displacement similar to a string trimmer,
but what small engine would have a big chrome exhaust pipe? |

Not sure what the R/C guys use these days.
I quit building and flying about '53-'54.
At one time must have had at least 20 different engines with names
like:
Arden, OK Herkimer, O&R, Fox, OS(Early Japanese), Spitfire, and more
that have evaded me.

1771) My guess at this is a combination egg scale and egg
candler (the light in the cylinder to the right). I
expect a wire from the ceramic base, but it could be some kind
of flame powered lamp too.
As for the units -- something once used to grade eggs. Not the
Haugh units, which require the egg to be broken. Ounces are
unlikely to go that high -- except perhaps for an ostrich egg.
Hmm ... one Google hit shows them as being classified by ounces
per dozen, so 40 oz/dozen is perhaps within reason.
1772) Looks like it might hold a smaller barrel so it can be tipped
to drain fully.
Or -- it might be for checking motorcycle (and really old
automobile) tires for leaks. Fill it with water, submerge a
portion of the wheel, and rotate while looking for bubbles.
1773) A press for assembling something like perhaps a roller chain
for a motorcycle? Or for pressing on or off a bearing? Stanley
made more woodworking tools and not much in the way of
automotive tools, but who knows?
1774) Perhaps for dropping aircraft external fuel tanks before
entering combat to improve maneuverability?
1775) stand for smaller compressed gas tanks Oxygen or fuel gasses)?
1776) A model engine -- and what it is mounted in looks too heavy
for a model aircraft, so at a guess I will say that it was for
a tether racing car -- which were popular until too many of the
tethers broke and too many bystanders were seriously hurt or
even killed.
I seem to associate the name "Wall" with the cars for some
reason.
Now to see what others have suggested.
Enjoy,
DoN.

Had a 0.60 that I was going to use to build an air compressor to shoot
dope but never got around to it.
For a model engine of that time, it was a beast.

Right. In the old days, even fairly small engines used spark ignition. My
uncle, who held several model boat records and built his own engines, had a
supply of miniature spark plugs from Germany during the '30s -- which, of
course, dried up. <g>
But I remember seeing those tiny engines in airplanes during the '50s. The
spark coil was almost as big as the engine, and resided in the fuselage
around where the cockpit would be.
Before glow plugs, the alternative was compression ignition -- pseudo
diesels. Of course, they're still around.

FWIW, I have an O&R bicycle motor -- probably around 30 cc or so. It's a bit
noisy for a bike motor but the old sucker still runs great. I don't think it
ever saw much use.
