There aren't a ton of points to oil but each one just put some (micro) drops on the points circled in the pic, run it, add oil if needed but running should work things loose/clean without adding a bunch and the needle tip applicator should keep the amounts good. A few of the circles are to reference the other side or a point on the other side of the inner part of the clock. Be careful of the balance staff (referenced in the video) as it is fragile and if "broken" you won't find anyone to try and fix it. Interesting thing I discovered, the clock for the 1940 and 1939 are 99.99% identical with the only difference being the balance staff is a fraction of a mm thicker.

Sorry these aren't the most comprehensive videos, these were just some quick shares for a friend.

the good part is that I have a nice working clock for the car. I can’t make this one any worse, so I may as well give it a shot.

I don't have audio on my PC so not sure what was said but I presume there was mention of the importance of cleaning and polishing the contact points which should be done first. If it doesn't wind properly, no amount of lubrication is going to keep it running properly! I recall reading that some people like to install a capacitor across the points which makes them last longer but I don't have details on this.

I've tried a lot of things

I use an electrolytic capacitor.
Think ceramic would be better.

Ran a wire hot side of coil drilled a hole in case . Ran it out backside.

Thru capacitor to ground.

Also.. put an on/off switch in only use it for car shows.

Thanks Corey, that is all very instructive. Where are the points and what does one use to clean them? I'm in the same boat as you, Don - I have a spare I can play with and not worry if I goof it up. BTW, Instrument Services came back to me and quoted $240 - $400 for the quuartz conversion. Not very specific, and they said to add a $34 up-charge for 6V. The kicker is a 12-14 week turnaround, so it would have to be a 'winter project'. Chris.

Part was me explaining how it works so not super critical unless you were curious. Assuming the inner workings weren't exposed, some simple air should be able to clean most dust out.

I got a quote back from Instrument Sevices to do a quartz conversion. It’s $434 plus shipping just for the conversion. They don’t sell conversion kits for my clock. The cosmetic work would be in addition to the $434. I won’t be going that route. I don’t need a desk clock that bad!

Anyone need a 1937 120 clock with no numbers and a mechanism that is likely missing parts?

Have you checked with the Dallas Zone Office? They may still be in stock.

I already have a nice one from the Dallas Zone.
