Classic Spindle inside a 5 inch float.  5 inch spindle floats are quite rare.  This make sense since there were a lot fewer 5 inch floats produced compared to 3 inch and 4 inch floats.  It's also less likely for the molten glass to form a filament and stabilize in place (to become a spindle) in larger floats.

This float also has a perfect stamp of WP #11 'Rivermouth' in the common triangular configuration.

Found on Hokkaido Island, Japan.

This Tohoku roller has a pinched end rather than the usual sealing button on the end.  The pinched end comes to a point that has some chipping from being a used working float.
