Hello All, This one has me puzzled ! It is 54mm diameter, it has two swirls, one rising up from the base, and another flat disc swirl positioned on top of the lower swirl. The central cane does not look familiar to me. The base is polished flat (no wear ring). it has not been restored in any way. The glass has a grey tinge and is not very clear. Has anyone seen anything like it?
