If the 1937 models are anything like the 1936 models, some had rubber shock mounts that were fitted into sockets on the inside front of the cabinet that would mate up with a pair of studs on the front apron of the chassis, so if it's like that then the one bolt at the rear is more then sufficient to keep the chassis in place. I believe that Renovated Radios sells reproductions of these mounts.
