With the Auburn / now Roseville Calif Bottle show approaching, I was reminded of a purchase I made there several years ago from a bottle digger in the area. He had a bucket full of AT&T two-piece tramps, said he dug them in a pit along old Hwy 40 near Loomis Calif. The interesting thing was they are all MLOD, crude, and have embossing that is somewhat finer and smaller than others I've seen. Hwy 40 is the historic main route east from Sacramento and the SF Bay Area. The telephone toll route along this road was also the original connection east, and eventually was part of the first Transcontinental Tel line. I assume AT&T installed these around the time the CD 190/191 design was introduced, specifically on their main routes. Found in a CJ article that the two-piece design was developed by by Augus Hibbard in 1889, he was employed by AT&T..
