Recently purchased this 1924 Pentical Andrews Electric Supply catalog and seen it had Lynchburg insulators plus 2 Illinois and Pinco pictured. I have never seen Lynchburg advertised in any catalogs before and previous PA catalogs just pictured Locke, Hemingray and Brookfield insulators. What is wierd is that they picture a CD 113 and not the CD 112 shape for thier No.31 exchange style and what looks like a CD 152 shape for thier No.44 (Cd154) style. All the rest of the styles pictured match up with known insulator styles. CD 106, 122,160, 162, 164, 145, 205 and 252. Since Lynchburg does not have a CD 113 or CD 152 that has ever been reported are these unknown styles or a catalog error? 1924 is also in the middle of thier production period. Just a curious observation. Thanks for looking. Take care to all.
