An interesting line-up of five glass insulators from Poland by way of Belarus. The large dark green 110mm diameter one on the right has the old style J STOLLE ,,NIEMEN' embossing on the skirt, as shown: [id=262214030]

The others are embossed woth JSN inside a circle, divided into three parts. Once the Niemen factory became Steklo Zavod Hemah the embossing became eother C3H in a circle or block letters HEMAH.

I'm not sure of the CDs for all of these, at least one or two are probably CD 600 (?). The small dark one is either a CD 470 or 472 (?).

A cleaner photo of the three insulators on the right side can be found if you [id=262566115]

The smaller ones have an 80 mm (3 1/8 inch) diameter skirt, the one second from the right has a 95 mm (3 3/4 inch) skirt and the big one is 110 mm (4 3/8 inch). The smallest one (dark cobalt-violet) may be smaller, perhaps 70 or 75 mm, it appeared on e-bay and has moved on to a new owner.

Apparently, the appliance upon which they are sitting is from Italy (I looked it up).
