UNKNOWN: Skeleton Soldiers & Skull Knights

This set of 8 50mm Skeleton Soldiers is around fifteen to twenty years old. The guy I got them from found them in Japan.  They were made in China and are a very soft rubber.  They come in black and black with silver highlights.  Originally packaged in plastic bags of 8 figures.  I recently found a bunch of vintage figures in a dark green that I had never seen before.

They have recently been re-released in a slightly firmer cream colored rubber under the name Skull Knights. The only company logo on the package is a cryptic "PMS." You can find them from UK sellers on ebay.  Some of the ones I received were a little smashed out of shape and did not stand well.  I dipped them in boiling water for 15 seconds then cold water and they straightened out nicely.

A molding defect makes this guy look like a different pose.
