Sorry I could not resist ..
Definitely pre-T :^)
Those are skeins, the cast spindles on the ends of the wood axle of a horse drawn vehicle.
Thanks Eric, I was just about to buy them for my 1909!

My 1890's Austin horse-drawn road grader uses something real similar on the front wheels - just larger.
Like Eric said, they're skeins for a heavy draft horse grain/farm wagon axles. It would be the 8th wonder of the world Kim if you'd ever get them to fit on your 09'. Basically those are scrap iron if you don't have the boxings (wheels) to fit that exact hub, same with buggy wheels !!!
Steve I have one of those Austin road graders.
Does yours have a brass plate on your's?
Mine is missing a front wheel and bearing like is described in the start of the thread, but I would doubt that those would fit.
I've not found a brass Manufacturer's plate - it has "Austin Mfg." cast into the main frame.
A friend of mine is a "chainsaw artist" and whittled me a new pair of wooden axles custom fit to my skeins - need to do some front end work though since we moved it to our new digs !
I thought maybe pre teen as in N R S or A B C maybe even K (sorry Ron) but now I think they are Pre Quadracycle. Probably were from the very rare and elusive prototype Henry could have made when he still lived at home on the family farm, before moving to the city.
They are from either a 12 lb. Napoleon or 12 lb. Howitzer so early to mid - 1800's.
