Action, who acquired the Revell line, re-released all the Dale Sr. liveries in their more detailed, upscale version (working roof flaps is the primary give-away, but the engine compartment and interior also have much more), and turned the Revell versions into the moral equivalent of a comparison of a Kyosho to a Bburago (think Ferrari F40). I actually, over time, replaced all the Revells I had with the Action versions, at the time, at great expense.
