I agree and there are also a couple of ambiguities in the various
links that refer to this car:

While the model was first  produced in 1934 this example appears to
have been converted circa 1940

Some say it had two reactors whereas the you tube clip suggests one
and a filtering system in the opposite fender

Reference is made to lighting coal and methane being produced 30
minutes later, the reality is that  it would be carbon monoxide that
was produced.  Even in town gas plants the temperatures were such that
methane was split and the carbon partially oxidised thus giving
hydrogen and carbon monoxide. This town gas would have run the engine
better and there are several archives showing cars with a gas bladder
on the roof, filled with town gas in UK.

It does actually look like charcoal rather than coal in the link to
youtube that Crispin sent and there may well have been a preference
for this or coke as it would mean the gas stream, though lacking in
hydrogen, would have been cleaner and thus contaminated inlet valves,
rings and oil less.
