Was told this was made in 1955? and was either Swedish or Czech. With such a broad attribution, was hoping someone here might recognize. Also, forgive me if in the wrong section .....was puzzled at where to start. Stands 6 1/4 inches high, is cased with a white interior, and fades from an almost flourescent green to a nearly black/green towards the bottom. Base is polished and extremely concave. Thnx for looking.
