That's the wide cylinder and an early shape. I have one, but mine does not have the "foot" yours does, and has no more than a broken vertical streak of brown, very like the slimmer cylinder first shown.

I really have no idea if the might have been running out of the silver nitrate - they might just have been experimenting.  ;D

There is the well known pattern in blue, with a large swathe of ochrey-coloured bits, spreading from one line  and being swept over the rest of the body, which were created using silver chloride salts.

They might have been trying to emulate that effect with the nitrate, but found it didn't work the same way.

Silver nitrate is expensive, but not as expensive as silver chloride, and they do both behave differently.
Silver chloride melts into a liquid when it gets hot.

I don't know what silver nitrate does. I've never tried heating it. ;D
It used to burn holes in my lab coat, to the point I kept that coat for silver nitrate use only.
It's very nasty stuff.
