What's the consensus, Ford Model-T hub wrenches, with non-Ford markings: are these aftermarket tools? or reproductions? or could they even have been included in an original Ford kit? This one is marked with a nice open serifed "H". Herbrand??

I would say it is an aftermarket Model T wrench.  I do not think this was made by Herbrand.

I think it may be for a Hupmobile....but I've had a hard time finding anything online to back that up.

It may have been made by Hinsdale.Their logo was an H in a circle and they made a lot of aftermarket stuff for Model T Fords including their G-20 socket set.

Maybe for this?

Going back through my pictures of old tools I came across another possibility: The Handleless Wrench Co of Jamestown NY. Here is a pic of their socket set.
