[time-nuts] General Radio frequency standard question

[paul swed]

Hello to the group.
I have to say I keep coming back to these pictures of the syncronometer.
Wow did it arrive in that clean condition? If not how did you restore it? I
mean it appears evenin the hard to get to corners there is no grime build
up.
Regards
