I removed it to tap into the 230V, so I could use 230V in the garage - discovered there was no junction box, just an outlet mounted directly to the plywood wall of the laundry room. The original octagonal junction box looked like it had been removed when the original dryer was replaced with one requiring a plug and socket.

The 100A ruling came into effect with the 1959 NEC. Regarding the dryer recepticle, the tombstone style 30 & 50A recepticle didn't require a junction box. The back part of the recepticle had a KO on the back or bottom for direct entry of the cable or BX. Also the code allowed the use of the neutral as the equipment ground. The 2008 code prohibits this practice.
