I think that the chain is half inch pitch (same as normal then) but the chainring only has a tooth at every inch, and these will engage the chain at every "outer" pair of sideplates, which are further apart, and therefore the chainring can be thicker.

You see this syle of sprocket on lots of old agricultural machinery too.

The chain is 1" pitch, cushion tyres, and mileometer.

So the chain is 1/2" roller to roller and 1" per full pitch, normal bicycle standard? What is usually referred to as 1/2" pitch.

Engaging every link on the freewheel and every complete pitch on the chainring?

Cool anyway 8)

wow!

forgive my ignorance, but what is the banding on the tread of the front tyre...it looks like it's been electrical taped on? :oops:

and is that a speedo??

Amazing..how on earth does it ride? it looks like you'd have to be a very squished/concertina'd rider to fit in there

Not exactly, this is proper 1" pitch block chain. It's also significantly wider at around 3/8" across the teeth.

In general the bike is very comfortable to ride, but no speed machine (especially in a headwind).

The mileometer (new york standard watch co) is a period piece, and yes, that was tape holding the tyre while the glue was drying.
