A. Model - Type 1, c. 1895. This was the first type of lock introduced by Diebold. As with many of Diebold's other locks this company took case damascene design to a high level. Diebold used an acid-etching method instead of the conventional milling technique to make their case designs. These cases were also gold plated. (see other two movement and three movement Diebold cases). These were made to coordinate with the rest of the design theme that would be found on the inside vault door surfaces. Imagine how beautiful this must have looked, industrial form morphing into art! These early models had no internal bolt mechanism, but used a bottom release lever in conjunction with an automatic bolt motor. This example has the very early 'rosette' logo on the inner case plate. Equipped with signed E. Howard movements. In 1902, Diebold switched to identical looking, unsigned movements made by Seth Thomas. Case #180. file 5

B. Model - Type 1, c. late 1890's. Same model as above. The early rosette logo is replaced by the hand engraved patent date of May 22, 1894 on the inner case plate. This and the simpler 'X' deco case design became the standard motif for Diebold. Equipped with E. Howard movements. Case #2267. file 40
