The old Esci M60A1 Blazer kit is now packaged by Italeri as the M60 Blazer. While the Esci base M60A1 kit is the best there is, the Blazer armor is not. I believe that the Academy Blazer set is superior, but the tank is worse. Verlinden had a resin Blazer set and it is nice. I've got an old set but have not gotten around to using it.
If you are looking to do a USMC M60A1 w/applique armor, both Tamiya and Academy do this kit. Avoid any M60 kit by Trumpeter/Wasan/MiniHobby. Terrible knock off of the Tamiya/Academy kits.
Note that the Israeli Blazer and the USMC applique armor are not alike. Blazer armor is reactive, meaning there is an explosive tile that dissapates shaped warheads on contact. Applique armor is just addtional ceramic armor designed to give the tank some measure of stand off against incoming fire. It is similar in nature to WW2 German schrutzen (sp?).
EDIT: BTW, I have all of the old Esci kits and several duplicates in AMT boxes. Some kits had silver tracks, others had a dark gray/gun metal tracks. I do believe at least one of them has tan tracks molded in the same color as the rest of the kit.
