I'm attempting to restore a German wooden cuckoo clock which belonged to my Grandparents, I imagine it is circa 1950s. The insides all work fine, apart from where the top of the pendulum (silver metal) is meant to touch the top right cog, thus moving the pendulum. As you can see from the photos, the part that is meant to be moved by the cog is further towards the back of the clock so doesn't rest against the cog. I've taken everything apart twice and nothing has helped.
I wondered if the cog may need to be slid down its middle pole slightly so it touches the top of the pendulum.
Thank you very much in advance for any advice.

Either the escape wheel or the verge will need flipped, can't tell you about the others from the photo. Taking photos for reference prior to disassembly will prevent this issue.

Definitely! Probably others as well. Don't know that you mean by cog and middle pole.

Wooden cuckoo clock? :???:

"I wondered if the cog may need to be slid down its middle pole slightly so it touches the top of the pendulum."
Translation "I wondered if the escape wheel needs to be slid down it's arbor so it engages the verge"

I knew what you meant Powerstroke, but I'm fairly sure the OP is pretty lost.

If the OP checks back in with that part figured out, the strike train is going to be a challenge to get right.

If the escape wheel is moving on its arbor (pole?) you have problems that are most likely above your skill level and that wheel is probably best replaced. (No offense intended)
What I would do is take all the wheels out and start over. It looks like you have all the levers in place on the front of the movement. You're going to have one hell of a time getting that back together with the front end levers in place.
Start by putting just the time side wheels in, close the plates and see if it works. Then do the same with just the strike. When you're comfortable with each train separately the. Try both at the same time. The strike train is more than just putting the wheels between the plates. It will need to be timed Sontheimern warning pin is hitting the tab on the lever while the gathering pallet is locked by the pin to work correctly. If you have any questions I'll try to help. You can pm me. Much better than being sent off to the library to find the info when you've hit a snag like this. Good luck.

It looks like the escape wheel teeth has some bent points. Those will need to be pulled straight again after you redo that train to get the wheels turned over.

The escape wheel is t even lining up with the pallets.

Yeah, but it's hard to see anything until the train is assembled correctly :)
