Chris,
Ford had many different types of wheels (non-demountable, demountable, square felloe, round felloe, Kelsey, Hayes, sizes of 30x3, 30x3.5, and 21 inch) and each was offered during different years. One of the best Model T books for identification purposes is "Model T Ford, The car that changed the world" by Bruce McCalley. Each year of the T is discussed in detail, and most accessories and standard items are identified. The frames are also covered by years and changes over time.
Great find, thanks for saving the items from the smelter.
Skip in MN.
