The first insulator is in very good overall condition. There is an annealing crack on the wire groove and a few pings and scratches. Sounds worse than it is. It is MLOD. The interior threading reaches all the way to the top with no extra dome glass. The front is embossed New Eng Tel & Tel CO. This is taller than the other two and has a wider wire groove.

The middle insulator has a few scratches and chips, all very minor. Just mentioned for accuracy. This style has the mold flashing around the upper wire groove and is embossed W Brookfield 45 Cliff St. NY. This has a slight graphite halo.

The third insulator, the short squatty 104, also has a few minor pings and scratches nothing serious. It's beefier and wider than the other two and has a shorter wire groove area. It is embossed New Eng Tel & Tel CO.
