Caldrahlsen Mechanicals was a droid manufacturing company[2] specializing in third-degree droids[3] based on the Core World of Esseles.[1]
The company produced interrogation droids for the Galactic Empire[3] and was the first to design and market droids specifically for the legal profession. Initially, these droids were met with a degree of skepticism but soon became commonplace within the Empire's legal system.[1] Their most notable product was the C4LR litigation droid.[2] Caldrahlsen's main offices and manufacturing plants were located on Esseles.[1]
