The third guy looks like he just took out a DVD drive from a computer.
heh, that was what I thought too
It looks like a music box. And it looks like a wind-up key he’s got inserted in the device. My guess is that he was some kind of repairman or machinist.
It’s a lock unit from a door. Leastways what I am guessing, hes holding the key, and you can see the screw holes where it would be secured in its pocket in a door
If you expand the photo you can see he’s holding an old antique lockset for on a door. The kind that was screwed onto the “in” side of a door, prior to the adoption of the modern Schlage or Kwikset, et al locksets which are inset INTO the door and only has the knobs showing on either side.
It’s a lock. I would guess he’s a locksmith or at least a carpenter.
