I don't know about the straight grousers but the drop center grousers If they are 24" are from a 1400, 1401, 1402 or 1404 imp. The bottom track looks like it has 44 grousers with every 5th one made with a plate (high grouser). That would be from an early 1400 or 1401 that didn't have an adjustable idler wheel. Early 1402's with the front idler had one 44 grouser section and one 11 grouser section so they could use up the tracks they had already made.
The 2 assembled tracks look like they have good salvageable grousers and would be good for spares to someone with one of the above cats.
