Thanks for the update. Looking good and I'm pleased its functioning well for you.

I'm guessing that somewhere in its life, someone has replaced the motor with that from a Mark V, which would explain the off-white colour. Not sure why the heat tunnel is white though, never seen a National Machine with a square and white tunnel and the Mark V tunnel is tubular. Maybe someone just painted it white? (See photo of a Mark V, below.)

Looks to be in much the original condition that mine was in: The internal wiring is the same, fabric wound stuff and the heater and the way it's mounted is the same as well.

The difference - and I was expecting it - is the rheostat. Yours seems to have - what must be - a later modification, which changed the "flat-pack" style of fixed-resistances that mine had, with a more up-to-date (for the time) wire-wound and circular resistance. I think this is also why Lanzetter added the additional ON-OFF switch, as the circular rheostat did not have an OFF position, whereas the "flat-pack" version that my older one has, has the first stud-contact not connected to anything, thereby isolating the motor from the mains voltage when turned to off.

What's still the case, is that they were both just as unsafe really - even by standards back then - mainly due to the unprotected, mains-potential connections on the rheostat. It would have been a relatively simple thing to incorporate some form of protective cover over that area, to make it safer.

All the same, a good acquisition as it is and an even better one, once you have spent some time on it.
Good catch!

Thanks Moose, interesting info re the motor etc. The ad did say the motor had been replaced at some point.

I noticed the rheostat was different to yours with the button type connectors but otherwise much the same everywhere else.

Oldhippy, that's what I'm hoping for, prior to this I've only ever cleaned by hand and had acceptable results but it's time consuming. There's something that niggles at me regarding ultrasonics so never used one but always fancied a proper watch cleaning machine mainly because I love gadget y things. 

Interestingly, I swapped a few messages with a fella on a group who started his career at Lanzetters, 2 brothers, one who dealt with the accrual watchmaking side and the other, the tools such as this and he worked on both departments, watchmaking after the tools section stopped.
