Any of you TOC guys recognize this early driver?

[Mike Rosseau]

Any of you TOC guys recognize this early driver? I've never seen one like it. The cog doesn't fit any of the early ND, Corbin, or Musselman hubs I have. I'm thinking maybe Atherton but I can't find any internal pics of those.

I think it might be the early (not hourglass) Atherton

looks to have low miles...

Here is a drawing of the early Atherton hub

 

[Rambler]

My Atherton hub is a different version from the advertisement posted by Giovanni however I cannot disagree with Giovanni's or ejlwheels's assessments. My Atherton driver looks similar enough to Mike Rosseau's driver that I'd say the possibility does exist that it could be an Atherton.

This Atherton sprocket looks similar to that on Mike Rosseau's driver.

This is the hub I was referring too (same as Rambler's second image)
which I believe is the earlier of 2 Atherton versions that I am aware of:

notice the driver screw sleeve with inner tabs at the bottom right.
It slides onto the slotted driver stem (as on Mike's example above).
One difference between this drawing and Mike's example
is that the bearing cone in the drawing is concave.
Otherwise, the basic design seems to be a match.

I believe the hub Giovanni presented is the (a few years) later hourglass model.
In the later hourglass model, the screw is integral to the stem of the driver.

I think that's the one.
