I hope I'm not misremembering, but I'm pretty sure they're Blue Box. There were sets from various historical periods, and I remember 2 types of boxing.
The one boxing was of four figures, an officer and three enlisted men (or the consul and legionaries, in the case of the Roman set).
The other boxing was a presentation boxing, that included 2 sets of four figures, one from each side in whichever conflict was depicted. The box was configured like a book, 8.5x11 inches, I think, maybe larger, with a lid that opened to show some text on the inside of the lid (left-hand), and the other side had a box with cutouts with the figures in blisters.
The historical periods covered Ancient Rome, the Napoleonic Wars, the US Civil War, and WWII.
For Rome, there was only the basic 4-figure boxing.
For the Napoleonic Wars, I only ever saw a presentation boxing, consisting of Wellington and 3 British line infantry, and Napoleon, and 3 Old Guard grenadiers.
For the Civil War, there was 1 box set each for the North and South, with Grant and Lee and Billy Yanks or Johnny Rebs, as well as a presentation box set with both sets.
For WWII, there were several sets: US Army, with Patton and three GIs; Wehrmacht, with Rommel (circa 1944) and 3 Ländser; and a British Army set, with Montgomery and three Tommies.
I have a vague memory of seeing presentation box sets for the WWII sets, one with the US and German figures, and one with the British and German figures.
The figures themselves are cast in white metal, painted in matte finish, and armed with weapons made in a soft plastic.
The Romans' shields were plastic, with a decal of a generic legion device.
I first saw these sold at WalMart, back around 1995 or 1996. They caught my eye, because the quality and style of the sculpt and the painting was very reminiscent of King-White/Reeves Intl, or early Frontline. The other thing that caught my eye was that they sold for less than $10 US.
Every so often, a box will show up on eBay, and also individual figures. When they're being sold as individual figures, most of the team, the seller notes that he doesn't know who made them.
Anyone else remember these, and am I correct that it was Blue Box ("BBI" or "Blue Box International" was the trademark on the boxes, I'm sure)?
Prost!
