I have not seen flexible rubber/leather/canvass? tracks this early. They are more like continuous belts and have no tread.
If it is in the USA: there was Holt/Best/Cat, Monarch, Bates, Bear & Cletrac. They all built tracked vehicles in the 20s and earlier.
I am new here and enjoy the challenge. Have not posted a pic yet.
Cheers,
