This pie seal was part of a 3 float lot that I purchased from Japan.

The float measures about 4 inches in diameter.

This tri-mold float has mark WP #67.  It's the common 'IIII' four hash mark.

The float is a nice dark brown color.

It also has net pattern frosting on the top half of the float.

This float has both Blue Swirls and Amber Swirls emanating from the seal.

It's an unusual 8 1/4 inch size float.

This float has mark WP #2 which is Kita 北. It's also known as FF to beachcombers.

The float measure 7 inches in diameter.

This 7 inch float has mark WP #2 'FF'.

It's a nice clear stamp.

These Corning floats are American made.

They have a unique bi-mold construction.  This style of float were also used to hold scientific instruments.

These are heavy duty floats made with thick high quality glass.

This float measures about 6 inches in diameter.

Duraglass is an American made float.

It's a machine produce float with bi-mold construction.

This float measures about 5 inches in diameter.

This Euro float has the Anchor mark 'BY5'.

It may have been produced in France or Germany.

It measures 5 inches in diameter and has tri-mold construction.

Mark WP #41-A is a rare mark.

The mark is comprise of an encircled Itarii 伊 symbol with the symbols Sa サ and Do ド above of the circle.

This mark has only been found on Sado Island.

All of the floats with mark WP #41-A are heavily worn; this float is not an exception.  It's has many scratches in the glass and lots of remnants of sea life.  

The ID seal has some major chipping on the bottom of it but just the bottom of the circle is missing.  All points of the Itarii 伊 symbol are showing. Fortunately, the Sa サ and Do ド symbols are also clearly visible.  These symbols are often mis-stamped, partial, or even missing on some of the other examples of WP #41-A I've seen.

This float is 44 3/4 in circumference or about 14 1/4 inches in diameter.  It's larger than the 13 inch size described in Walt Pich's 'Glass Ball Marks' book.  I'm not sure how or if that effects it's rarity.

It also has excellent provenance having been found by Kala & Aragon Ellwanger on Sado Island, Japan in 2019.

These Russian numbered float are hard to find and quite rare.  This float has the '3.' mark.

As with all the Russian numbered floats, the float itself is bi-mold construction and has a first generation style of seal button.

The float measures 3 inches in diameter.

Extremely rare Black Pumpkin.  There are somewhere around 20 black pumpkins known to exist and they're highly desired by collectors.

This black pumpkin appears to be made from a brown color. 

FYI - No black pumpkins are actually made from a black color base.  They're all made from either blue, green, or brown color.

There are no patches on this float.

This pumpkin measures about 34 1/2 inches around or about 11 inches in diameter.  It's about 9 1/4 inches tall at its tallest point.

This float has excellent provenance.  It was beachcombed by Lydia & Ken Rush in Northern Japan in 2015.

This smaller float really isn't even a float (yet).  In fact, if you put it in water it will sink.  But there's more to the story than just that.

When I worked in the glass bottle factory we create "perform" bottles.  This was the step before we blew the bottle to its full size.

This perform glass fishing float is hollow on the inside.

What makes this perform float even more interesting is that it has been sealed.  To understand the reason why this perform was sealed, see Stu Fransworth's explanation below.

This perform float is quite heavy.  It may be equivalent to the weight of a 9 or 10 inch glass fishing float.

It also has some nice amber swirls in it.

When I purchased this glass fishing float from Evan Buffington, he shared this correspondence he had with Stu Fransworth about this float:

Stu Fransworth on May 31st, 2021: 

"Hey Buddy; I can help you with this float.  It is called a bottle float, is Japanese, and were blown to be a larger float such as a 26 to 38 incher depending on the girth of the glass.

I knew a lady that had one back in the late 70's and it was so heavy it just sank.  How the hell it made it onto the Long Beach Peninsula is anyone's guess.

Do the water trick.  If it sinks, then it was made for Long Line Tuna Fishing.  If it sits low in the water, it was probably made for Long Line Cod Fishing.

They don't care unless it's just too big a glob and either they use it or throw it into the kiln and do it over again.

Nice float, if you ever want to seel it keep me in mind."
