Anchor
There are several Anchor markings, the origin of which and the production dates are unknown. But there is some similarity to known British made floats that may be taken into consideration and suppose that the Anchor marked glass floats are of the British origin. The similarity is somitimes in the glass thickness, color of glass, the molded (seamed) glass form and the location of the Anchor marking. It is sometimes located on top of the glass. The Anchor marked floats are of different colors but all of those we have met are of the same 5" size in diameter.
