Wilhelmshütte
Wilhelmshütte (Nienburg, Germany) operated in the period
1891-1997. The glassworks (established as a subsidery of Stralau
Glaswerk) manufactured bottles, container glass and glass fishing
floats. The hand-blown glass buoys marked with an embossed 'W' in the
house on the sealing button were produced in 3-10 inch sizes in
diameter and of a variety of colors: amber, light green, bottle
green, dark green. There is also a 'dog-neck' type of the fishing
floats made at Wilhelmshütte and the ones we came across measure
9 inches long and 6 inches in diameter.A huge thanks to Paul from Denmark for providing us with the source about Wilhelmshütte.
