Agfa Bellows Camera, Self-Timer, SEKONIC Lens, Antique, Showa Era

Retro Showa-era items - a set of camera-related equipment.

・Agfa Camera (pictured)
I understand it's an old camera, but I have no idea what kind it is.
I managed to extend the lens, but I'm afraid to try anything further to see how to get the lens to come out, so I haven't confirmed it.
Operation has not been tested.
As seen in the images, there are scratches on the exterior. Made in Germany.

・Sekonic Autoleader
Comes with cover and strap.
I don't know how to use it or its purpose, so I cannot confirm if it's working.
It was stored with the camera, so I'm unsure if it's an accessory or an optional item.
Please check the images to confirm its intended use.

・Lens hood? Metal hood?
I believe it's made of iron and is meant to be placed over a lens, but it was also stored with the camera, so I assume it's an accessory.
I also don't know its intended use, so please check the images.
It comes with a dedicated case that closes with a button, but it feels a bit tight.

・HANSA Self-Timer
This was also stored with the camera, so I assume it's an accessory.
Comes with a case and instruction manual (which I couldn't understand even after reading it).
Please check the images to confirm its intended use.

That is all.

These items belonged to my father and were stored in a storage room for a long time.

As mentioned above, I do not know how to use them or how to test their operation, so I cannot guarantee their usability.
Also, as they are old items, there are some dirt and scratches, but I don't think there are any major damages.

Please consider this information and make your decision accordingly.
