the bonnet plug for top of hydrant

Isnt it kinda small for that?

I was thinking more in the way of one of the old old hydrant with the side plugs....

My guess is a wheel off a belt drive, similar to a serpentine belt setup. Maybe the threads aren't threads but grooves where a grooved belt sits in but on a smaller scale.

This appears do be bigger than a quarter, maybe a half dollar in size; right?

Cleaning will help.

Well, some of these guesses are way off in size.

I agree that's why I re-evaluated my theory of the hydrant...but some of the older ones do have small plugs in them!

That's a good one. Hope an clear answer is found. Love a good mystery.

It does look like a serpentine belt pulley. But I dont know if they make miniatures. I would like to see another pic after cleaning.

I will try cleaning it up.

Grey arrow....is this plugged or is it dirt? Red arrow.....Is this some kind of a pin or lever?

 

[98 gt]

it looks to me like some kind of vent cap...

 

[98 gt]

what is the diameter?

 

[Nashoba]

Oddly enough it struck me that it might be a part of an old gas burning lamp?
I know I have seen one of these before SOMEWHERE!

Is that a dime or dollar beside it?

the red arrow points to a set screw that would keep it from uscrewing its self, which makes me think its not normally screwed in all the way, plus the small vent holes tells me its part of some type of adjustment for a flow regulator I am thinking some type of factory set appliance regulator

 

[pgill]

Is the hole in the centre all the way through?

God bless

I missed placed the darn thing, Recently put in a wood floor and had to move everything. The red arrow is pointing to what could be a vent. I believe the hole does go though and the coin is a dime.
