Pre-1917 Drucki-Lubecki insulator found in Russia. The height is roughly 4 2/3 inches. It's interesting that on the one hand the insulator has standard Russian configuration (used by D-L factory in that period) and on the other hand it has the green stripe which is a common feature of German/Preussian insulators.

The insulator is fixed on it's hook with bismuth or lead.
