Nikonos III with Nikkor 35mm + 20mm lenses, used, with defects, junk?

I love Nikon's designs and ended up buying too many.
As a result, my family is giving me the side-eye (T . T).
You don't need this many cameras!
You're not even going out to take pictures!!
Besides, they're just in the way!!
That's what they said (T . T).

The product includes:
Nikon III body (used)
35mm f2.8 lens (used) and 20mm f2.8 lens (used).

- Brand: Nikon
- Model: Nikon III
- Lens: NIKKOR 1:2.8 f=35mm
- Lens: NIKKOR 1:2.8 f=20mm
- Shutter Speed: 1/500 sec
- Film Type: 35mm

This is a difficult to use item.
The B setting on the shutter speed is broken.
Since it's a difficult to use item, is it considered junk?
I'm not sure about the definition of junk, so... I apologize (m(_ _)m).

This is a waterproof camera... however, due to age-related deterioration, it's unclear if the rubber packing can withstand the water pressure for underwater shooting! If you plan to shoot underwater, please do so at your own risk (m(_ _)m).
I would be in trouble if you complained that the camera broke after underwater shooting!

No claims, no returns, please (m(_ _)m).

Thank you for looking.
