The pair of transformers for sure informs you that this is a very early toy train accessory or power course. The sped setting has small ended metal bumps" to incrust or decrease the speed of the train. The inside of the box has lots of thicker coiled wire, and the box also has stamped out ovals to allow for the heat to dissipate. Also, take a look at the electrical cord and plugs that would go into the wall sockets. I barely remember these cords from the 1950's. Also I've seen exterior cloth covering on very old wiring in old house basements in the ceiling beams near me in a part of Montreal called N.D.G. (Notre Dame de Grace), I last saw this wiring in the early 1990's when my wife and I were looking to phrase a house. I'm sure that by now (2014) the firemen who every several years will inspect homes here for smoke alarms would have certainly notified homeowners of the danger of such old wiring. Also, I'm 100% sure, that any real estate agent would have made the comment about the danger of such old wiring!
Finally a beautiful street lamp. It's made from cast iron and hardwood as the base. The bulbs are "vintage", and take a look at the lamp base. Wiring from a transformer or wall outlet would have had small c-shaped clips to connect to the brass nuts and bolts.The nuts would then be tightened to the pair of c-clips to keep the wiring ends firmly attached!
