got this recently with a bunch of T parts. any clues to what it is?
Looks like an accessory rear wheel axle for towing a Model T to the garage when an axle has broken?
Would the black cylindrical part to the right fit in place of the outer Hyatt in a rear axle?
If a rear axle shaft breaks, you install that and re-install the wheel so you can tow the car on all fours.
