Like the Combat sets, the Bivouac series are essentials, and were available in both window box and carded formats

The tent set was available in a rare small window box in 1964 only (7516, above, courtesy Vectis Auctions), and was simultaneously released in a larger window box (7513) (below) with a machine gun. It's an accessory that rarely gets set-up in collections because of the space it takes. The design is great and it deserves more recognition. You're lucky if you can find the very rare early issue tent poles with plastic tabs rather that the standard metal pins.
Notes on Variations
Mess kits (above) come in an early variety with a molded loop and no loop on the lid, and the more common type with a looped lid. The earlier is marked only Hasbro, the later has the addition of Japan. A third type showed up during the Adventure Team era.
