I have both kits and just compared them.
The kit to make the M109, A1-A2, G, and E4 is the one to make the standard NON Paladin version of the kit. It looks like the parts to make the E4 version build into the Isreali version, but I am not sure as there are NO MARKINGS inthe kit for the E4 version.
The Revell of Germany kit will build the M109, the A1-A2, and the G version, as well as the "updated" G version. It does NOT have the parts to make the E4 version, but has a load of parts on a new sprue E to make a better German version...including a new barrel with "sagging bag". It also has the "diehl" tracks, not the normal ones associated with the M109.
So there it is. Also, try
www.squadron.com to see what they have...(I could not check it just now.)
And there are many goodies to add to a M109A1-A2...like the warriors (ex-KMC) interior and exterior parts. This really makes the kit stand out.
BTW, I just finished the Paladin and I built a M109A1 years ago...the kit builds best into a M109A1. As you work away from it, it gets to be more work to clean up correctly. Just so you know.
