Well, they are on all the Torpedo 3 and 5
speeds which are extreamly common (we typically
don't have the British brand at all) - also,
Torpedo was officially or unofficially (?)
copied or closed-to copied in Soviet-block
countries, so there are many "pulleys" -
I think it might be just random I have the
"single wheels" but not the doubles... Anyway
I suspect doubling them up will work just fine
because the wires are calibrated individually
at the hub!

I tried to find some photos of a "Torpedo 5", but none of them were
very clear although they seemed to show the "wheels", and the cable,
above the top of the chain, which I assume has something to do with
where the cable attaches to a gear change mechanism.

But in any event I can't see any reason that they wouldn't work, but
if they didn't it should be pretty easy to correct any problems..

I tried. Many photos of the entire bike and the rear hub but no
pulley.

O.K. pulleys.... I though that I remembered you saying "wheel" :-)

OK, I get a photo!

But it looks very much like the single wheel
version only it has one on each side!
The wheels are identical what I can see and you
can pick them apart and move them between the
versions as they sometimes break (being
plastic).

It was AMuzi who just know tought me better

A couple years ago I converted an old custom frame to a 3-speed, using a
Sturmey-Archer hub I had on hand. At first, I used a plastic pulley
just like that, but eventually abandoned it. Due to the long lug
points, the pulley had some misalignment, and the cable would derail and
eat away at the pulley. I've used the brazed on guides at the bottom
bracket ever since, with no serious problems.

I got that. English is not Mr Ber's first language but
"Bicycle Rider English" is one of my acquired patoises.

c.f. 'flippers', 'squeezers', 'rat traps', each of which may
describe several different objects depending on context. You
may be familiar with the interchangeable terms, 'tire',
'rim' and 'wheel', as in "I have a flat wheel." or "My tire
is bent."

Then there's "tar" vs. "tire" in the southern U.S.

That caused me grief on one occasion. I'd ridden past some "Road
Closed" signs on a long hot rural ride home from work, because any way
around would have added tens of miles, and bikes can almost always get
through.

Anyway, some guy in a passing work truck yelled some sort of warning
about my "tar" or some other "tar." My tires looked fine, so I rolled on
- and got sprayed with a fine mist of genuine TAR from a truck preparing
for road paving.

The steel pulleys tend to rust and seize - the plastic pulleys, only the pin
rusts and that wears the pulley.

So the plastic pulleys get wobbly - but they keep working longer.

A modern nylon plate under the BB works very well. I added
one in 1985, no trouble since.

No, it is apparently not, but never the less he does better at it than
some "Americans".

I'm reminded of the fellow that came in the shop one day wanting to
know if we had a "fat thread" bolt.
