PART 2 *** Any factory or plant guys out there recognize these things?

[mn9000]

A few more things that we found in the abandoned factory, not sure what they are but they definitely appear to be of very high quality construction. Stamped with "H.H." followed by 4 digit numbers.

Each of these parts has a grease port. Are these individual parts taken from a single larger unit of some type? Maybe a lathe or a tooling machine? Thank you guys very very much for having a look!

ps--- are these brass or bronze?

Just machine parts. Could be from the same bottling machine as the previous parts. one big housing with sprocket could have been the end of a flat chain conveyor on that same machine.
