Got this on eBay from a Canada seller that might be on ICON ? Listed as a foreign insulator. An identical one sold for more in another auction where it was listed as Poland so i guess tht's right correct me if I'm wrong. Had no idea it was this big and heavy my foreign collection is starting to take off now. It says J. STOLLE NIEMEN with two prism stars below the L's in STOLLE. Would appreciate any history info
