I am fortunate to have been given a complete period Starrett socket set (the ratchet is soaking to lubricate the mechanism)

Can anyone tell me the functions of the three items in front of the box please?
The tiny bar has a taper and will fit in the hole at the base of the square section in the pointed part.
The pointed bit is apparently solid. It can be gripped by the item in the lid.
I have no idea what the part that looks like a large rivet does!

So; no-one knows!

But I have now discovered, by more cunning and persistent application of Google's services that the pointed item is a drill bit holder. There is a tapered square hole inside the square shaft. If you hold the knurled bit and turn the square, it winds out, presumable following the drill bit. But I don't know why it has a point, unless that sticks into a wooden pressure plate.

The 'rivet' fits inside the hollow socket square section to proved a hand pressure pad - or maybe to stop the socket falling out. It should have a spring blade on the side of the shaft.

But that still leaves the small tapered tommy bar. It fits the hole in the square......but why?

Not the same set but similar from a 1919 catalog. Or maybe it is the same one?

It's apparently almost the same content but a different box.
Mine is also a 443, but maybe a 443B

The write up in the ad doesn't mention the drill holder but it's on the picture in the lid, as is the small tommy bar.
The 'rivet' isn't shown.

I wonder what's in the top left corner of the lid?

Also, $15 in 1919 was a lot of money. Over $200 in today's money
