Two impressive free standing spindles run from the seal to the base of this 4 inch float.
One of the spindles is an almost perfect straight ribbon spindle without any twisting at all.
The second filament of glass is a ribbon spindle with curves and twists that you usually see in spindles.
Amos Woods estimated that the relative frequency of finding an internal spindle inside of a float at 1 in 1,500. Finding a double spindle is much rarer. Finding two outstanding ribbon spindles in a single float is extremely rare.
This float also has a partial stamp that could be WP #130. A couple of the 'Sa' サ symbols are clear and they seem to fit in with the standard WP #130 Sa サ in a triangular configuration.
