OK, I finally found my King White CD! I knew I would; it was stuck in a file in one of my filing cabinets. That's what I get for straightening up my office.
The catalog lists 6 samurai figures:
for clarity:
SMR 1 Sekigahara 1600 Tokugawa Ieyasu
SMR 2 Tenko-no-ran AD 940 Taira-no-Masakado
SMR 3 Sekigahara 1600 Bate Masamune
SMR 4 Sekigahara 1600 Honda Tadatsugu
SMR 5 Kuroda Nagasama c 1590
SMR 6 Samurai with naginata c 1590
The catalog has this image of the 6 six figures:
From this, I'm convinced that the first toy soldier in your photo is SMR 2 Taira-no-Masakado, Brad. It looks like the tip of one of the horns on his helmet has broken off, and in your photo, it looks like his scabbard may have broken off, too. That's not unusual; those tended to bend easily at the attachment point and snap off.
Looking more closely at the catalog photo, I agree with Tom that all 3 are King White. The middle figure is SMR 4 Honda Tadatsugu, missing a spear, and the one on the right is SMR 6 Samurai with naginata. He's missing his spear, too.
I hope this all helps! It's been fun digging the info out, and it's always great to see posts of King White figures. They were among the first toy soldiers I collected, as opposed to figures I cast myself or bought and painted. And as we've said, these were the original "Chinese style" figures, the granddaddies, as it were of King & Country and Frontline.
Prost!
