Small Jumbo Rollers are rare and highly collectible.  I've been told there may be around 20 of these floats. 

This small jumbo roller is extremely rare since it's the only unmarked one known to exist in collections.

It measures about 9 5/8 inches in length and is almost 2 1/2 inches wide.

These small jumbo rollers appear to be made from two different molds.  It's believed they were produced by Daiichi Glass Company in Hakodate, Japan.

I purchased this float from Shannon at the 2021 Beachcombers Fun Fair.  It has excellent provenance since Shannon bought it from Woody Woodward who found it in Northern Japan.
