First time the covers are off in a while, it shows

When it looks like this on the inside, it's been a while since anyone removed the covers.

This loose, woolly dirty dust must have taken some time to build up. It will need to wait in the shed, until a nice sunny day to give it a first cleaning in the open air. 

It'll overall need a bit of a re-build; the machine is blocked and several parts are missing. This pinwheel calculator will be an enjoyable challenge later this year - but for now kept in quarantine.

 

There probably are too many missing and broken parts for this to be viable, at least for a while - that broken lever in the image below looks 'fatal'. It will require some new castings or hard-soldering not yet practicable.

 

For now in storage it goes - a pity, because these California-made machines are fairly thin on the ground here (and it's an early one, the 49th made as serial number 70049, carriage assembly number A1007).

Astonishingly, the pinwheel assembly itself still works just fine!

Fail :/

(for now)
