This small 2 1/2 inch float has a tiny stamp of WP #130 'Sa サ in a Triangle'. 

It actually has two WP #130 marks.  One is clear and complete; the second stamp was over-stamped a little.

Unusual tri-mold that's marked on the seal.  There are two hash marks on the seal; making it mark WP#65.

It has four hash marks on the shoulders; making mark WP #67.

This tri-mold float is almost completely covered with net pattern frosting and has a nice orange peel effect on the surface of the glass.

It has excellent provenance having come from the ex-Aaron Krogh collection.

Undocumented mark that's similar to WP #31 'Chohokei' or 'Ichi' except that it has 3 Dots aligned along one of the sides of the rectangle plus 2 Dots that are located on the edge of the seal button.

Since the primary symbol is Ichi in a Box, I'm assuming it was produced by the Nichiro Fishing Company on Hokkaido Island, Japan.

Great example of a float with barnacles.

This is a 14 inch spun-fused float.

There's a net embedded in the barnacles.

Beachcombed by Truett Carmichael on Matsu Bay, Japan.

Amber Green Swirls emanate from the seal and spiral throughout the float.

Pie seal that has the wider spacing between each line.

This float measures about 12 inches wide.

Double Ball float with a double seal to completely seal off the top.

The inner ball measures about 1 inch at its widest.

This float has excellent provenance having come from the ex-Jim Watson collection.

Rare undocumented mark that appears to be an encircled Chou 長 symbol, so it would be Maru Chou.

There are some questions about the kanji.  It could be: Chou - head or leader, Osa - head or leader, or Naga - long.  This symbol could also be the Japanese trademark Yagoh.

It's stamped on a 4 1/4 inch float with tons of bubbles.

This is the only known example of this mark known to exist in collections.
