--metal tracks with rubber pads
--metal idlers with support bar
--metal sprockets
--metal support arms and springs
--Ultimate Edition II gearbox/motors
--360 degree slipring
I've also ordered the Tamiya Pershing sprue with the 0.50 cal machine gun, since it's much nicer than the HL version. I will be attempting to replace some of the more obvious molded-on features, and backdate the M1A2 to an M1A1, 3rd Infantry Division, OIF 2003.
Hope you like it! Cheers, Tom

Casting numbers added using numbers shaved off sprues:
