I believe he used/is talking about the Dragon "Orange Box" Super Value Pack boxing of their M26A1 kit. It has the M26A1, parts for either a late WWII T26E3 or a Korean War M26A1, two types of tracks (DS T80E1 for Korea; plastic indi-link T81 for WWII), Dragon's WWII US Anti-Tank Team figure set (6149), and four extra weapons sprues that include a flame thrower, a bazooka, and a bunch of different personal weapon options.
These Dragon "Orange Box" Super Value Sets are usually older kits updated with DS tracks, small PE frets, or a few updated pieces and extras like the figure kit added. They are a good deal if you are not looking for the latest, greatest release. The added pieces are usually quite good and they can come out great, as can be seen above. The price is good too, usually around $30.
