Thanks for the images Nick, they definitely allow for a careful
comparison.

As you say, in spite of the overall similarity, they are readily
distinguished from the Heflin object by visual inspection.

The image I have for the Bachmann wheels is not particularly
good, see:

I spoke with a Credit Valley representative, and apparently they
also carry Bachmann, so we may be looking at the same wheel.
However, I could be persuaded that yours are very subtly more
'Heflin-like', better matching the ramp from the outer rim
toward the center. Neither is a very good match to the outer-
rim-to-inner-hub diameter ratio.

I am also of the impression that the object seems closer than
claimed, based on the darkness of its shadowed areas.

During the flurry of Heflin discussion last summer I tried to
obtain a range constraint based on atmospheric extinction, but
it turns out that visibility at the time of the photograph was
substantially greater than originally thought, and the result
was inconclusive.

At the range associated with a model train wheel, brightening of
the underside would of course be dominated by light from the
ground and/or Heflin's vehicle itself.

In my conversation with Credit Valley, I was transferred to a
gentleman who was quite well-versed in the history of model
trains and their accessories. He asserted the following: in
America prior to 1969, a metal model train wheel at 1:32 scale
or larger would have almost certainly have to come from a live-
steam set imported from England, with the overwhelmingly likely
manufacturer being Roundhouse, or possibly Astor.

I must say that my visual impression of the Heflin images makes
the model train wheel idea hard to swallow. If that's what it
is, he achieved a remarkable effect. Perhaps others have
developed optic/geometric arguments that would rule out such a
tiny, close-range prop.
