Kusama Clock, Showa Retro, Wall-mounted, Cuckoo, Pendulum Clock, Junk Item, Free Shipping

This is a Kusama-made clock I previously purchased at auction.
I am selling it because I have too many antiques. Would anyone interested like to have it?
The pendulum swings for about 3-4 minutes but then stops. Is it out of oil?
I believe it requires maintenance or an overhaul. The dial is made of aluminum and is solid. As shown in images 7 and 15, there is a gap between the crown and the main body. As shown in images 3 and 14, there are about 4 small nails under the exterior dial for what purpose?
The connection of the pendulum rod also appears loose. It may be damaged.
The winding key is missing.
There may be other overlooked issues. Please judge from the images. The size is approximately 76cm in height and 32cm in width.
We await bids from those who understand the good and bad points of antiques.
Direct pickup is also available.
If you are near Atsugi City, I can deliver it to your doorstep by passenger car.
