The -100 series speed brakes have no auto deployment. The -200 series does. I did fly a 727-200 without the auto speed brakes. Maybe some early 200's were made without auto speed brakes. We had some weird planes in our fleet. We has an X TWA plane that had the overhead and FE panel switches reversed. The FE panel UP was Off and down was ON. The overhead was F]foward wasoFF and backward was ON. TWA was the only company that ordered them that way. It really sucked.
