If you're looking at a M&H you are looking at a pretty desirable insulator. Now if you are looking at a blue M&H in super condition you are looking at a real rare animal. The bold embossing is M&H PAT. MAY18 1915 Beside this fantastic blue M&H (U-189A) included is a brown M&H and a U-189 Peirce. If you look closely at the left hand side of the Peirce at the base, there is a tiny white spot. That little flake is all I see for damage on these three super insulators. Offering the group for $650 and that includes the shipping and insurance. I can't remember if a blue M&H has ever been offered here on Icon but I'm sure it will be a long time before you see another.
