So, this was purely an impulse purchase.
The more I get into this, the more I find wrong. Apparently this clock is much older than I thought.
It's apparent it's been worked on over the years trying to keep it going.
I'll post more when I pull this movement apart and work on it. I stopped in the middle of disassembly to post this.

For now can anyone tell the Mfg, and/or age of this movement?
It's marked with a large [CM] in a rectangular box.

It's an Asian clock. Others can probably look up that brand for you. Willie X

Thanks to those who replied
I actually suspected a Korean movement before I pulled it. This movement is a mess, make-shift springs, so many things are bent out of place. The butterfly is bent up but functions, the crutch, even the suspension spring has a bend in it.
Sadly I think it needs an overhaul and a cleaning. Oil everywhere.
It has a paper replacement over the original dial.
What was I thinking:???:

Those were sold by Sears Roebuck in the '60's. I've found them to be a major headache to get running reliably. The recoil verge/wheel is not well made. The pendulums were way too heavy as well. Yours has been replaced.

Thanks Shutterbug,
Funny I was just working on that very thing. I replaced the bent suspension spring hoping to solve that problem. It just refuses to run. The anchor/verge is not correctly turning the escape wheel. I thought the crutch was out of alignment. I 've been trying to re-bend it back to where I think it should be. No joy.
I just walked away from it for a while to rest my eyes.

Insanity is doing the same thing over and over and expecting different results...

I have seen quite a few of these clocks over the years.

Often presented as antique.

The carving has a very Asian feel to it.

Overall, not the best quality but at least an eyeful for the $$.

Insult to injury is that I think the dial has been over papered.

There was a Bulletin Article about the Korean clock industry:

243_275.pdf (nawcc.org)

Though this particular clock is not pictured, some of the variety of clocks that industry produce are.

I actually was successful in getting this movement to run. Besides the obvious, the crutch was so twisted and bent out of shape it took me quite a while to get it into a "best guess" position. It's currently running for a few hours now. It's running without a pendulum or bob attached. Always a good sign in my experience.
I don't expect perfect with this movement. That being said, the crutch/anchor/verge still seems a bit off, not smooth.
If anyone could spot something I'm missing I would appreciate the feed back.
I'm uploading a video clip of it running. This has not been thoroughly cleaned yet, so pardon the appearance

The video is not very clear but the crutch wire would not have that big bow out to the left. Also, get closer and add the pendulum to slow things down. Willie X

Will do Willie X, but I think its pretty clear. Maybe not on a phone but on a computer, looks fine to me?
This crutch was so bent out of shape, I just kept repositioning it till I could get the movement going on it's own. I never said it was right which is why I asked for advice.
I have a 175 year old clock, that has a much better movement but a similar crutch/anchor setup. I have been using this as a gauge to reposition the crutch in question.
Even though it's running for days now, I know it's not right. I have much more play swinging right than I do left of center when I stop it to check and/or calibrate the entire swing.

How does the pin that holds the verge look? How does that hole look? You might have issues there. I studied your video but that part is not too visible.

Tip, bend the crutch wire near the top for large adjustments and near the bottom for small adjustments.

I would start over and get rid of that big bow to the left.

There should be a gentle bend at the top (to the South East) and a sharp bend near the bottom, about 1/8" West of the crutch loop. The rest of the crutch should be straight.

In the photo, your clock's going/time spring is run down ...

Thanks again for the replies, it's much appreciated.
I did straighten that crutch Willie X. I took that big bow out, but of course now everything is off. It looks as if the verge is barely engaging. So back to square one. I'm concerned the brass crutch will just separate/break from the verge and then I'm up a creek.
I took a new video of it running after re-bending the crutch.
It's only running for 5-10 minutes before it completely loses momentum.
FYI: The spring is 12 1/2" long, and the pendulum is 19 1/2" attached so this is a really long 32" (and heavy)
The video was taken with all that attached.
I will try to upload it later this evening.
Shutterbug : I'll take a look at the pin holding the verge


Thanks again

Is there a second hole in that pallet strip? It's not normal for the entrance and exit pallet dropoff spacing to be that different. The entrance pallet is close to twice as far from the pivot pin as the exit pallet. They should be about the same.

Looks weird to me as well Willie X, which of course is why I post. I took a closeup of it, and it appears thats the way it was designed. I'm posting two additional pics.
1: readjusted crutch
2: closeup of the verge, pallet, escape wheel.

All I know is this crutch in this position will not work for any length of time.
See below:

You can make it run a lot better, if you are willing to make a few changes ... "the way it was designed", is yer problem!

I wound up the time side spring and started it again. It's been running about 14 hours now. Go figure.
The only niche I see is where the suspension spring rod and the pendulum hook are attached. There is a slight jiggle both on entrance and exit of verge as the pendulum travels left to right. Maybe it's just the overall length amplifying it at that point?
What changes are you referring to Willie X?
