According to R.H. :
This week's photos have just been posted:

O.K. Posting from rec.crafts.metalworking again, and hoping
that it gets properly posted this time, unlike the previous two tries.

545) Pedometer -- counts steps and displays them in units of
miles based on stride length.

546) To hold fireplace materials, perhaps?

547) Speaker from a drive-in theatre. Volume control knob is
long gone -- perhaps broken off the shaft.
The hook on the back keeps it in the window of the car.

548) Nozzle of a fireplace bellows. A rather nice looking one,
at that.

549) Hmm ... not sure why the end is so sharp. It is obviously
designed for a wrench to grip the square at the top to tighten
it. I suspect that the two square eyes on the casting link to
arms which apply leverage to clamp something as the screw is
advanced -- but what is being held is not clear. I guess that
I will have to wait for someone who has seen one in service to
identify it.

550) Perhaps for perforating the soil around a potted plant? That
seems within the capabilities of the spring as described.

Now to see what others have guessed -- after making sure that
the article really gets posted. :-)

Enjoy,
DoN.
