Hello Allan,
in the PCA Bulletin Susie Kaplan Jacobson wrote about Masonic symbols in paperweights-
there are illustrations similar cross weights- implying masonic and "rosicrucian" symbols- and are attributed
to the NEGC makers. (2012 Bulletin page 61 ff.)
The green flash ground is definitely not a known feature to Friedrich Egermanns paperweights,
and Egermann's canes are definitely different- even the simplest are composed by overlaid "hollow" tubes,
the more complex are bundled star rods in many variations...
The canes in your weight are more reminding of NEGC regular makeshift,
Anyway a very nice weight, Kind regards, Erhard
