Picked up a small 12 insulator collection recently consisting of 6 commons and these 6. An unusual grouping for sure. Third party transaction so don't know the original collector. I do like the collection though. The 143 has great amber swirling around the threads and into the skirt - tough to photograph. The H.G.Co. 162 is a very nice red-orange with fairly minimal damage for one of these. The other pieces are mint. The green foreign piece is an Isorex HC64. The 164 is a Lynchburg - not rare but I don't run into them here in Montana very often. The others you know by sight. Enjoy.
