Unidentified box in wall

Hi, I'm helping my friend do some restoration on his 1905-1910 colonial and we came upon a small door on the wall that opened to a small box with remains of electrical leads - Can anyone identify the use of this box - see pictures

Tim,

That is where a knife switch was located. A disconenct for the entire floor. Would have been nice had the equipment still been in there. We have a couple of them behind a small door on each of the upper floors of our house. They were still in use until about a year ago when I re-wired the house. I took our house from a 60 amp to 800 amp service.

Tim,

This is what is in my house serving the third floor. It is now dead, but I am keeping this in tact. There is one 30amp circuit coming from the main meter box. Yes, this is connected directly to the top of the meter lugs. No protection at all. The knife switch is off to the top left. There three different circuits that used to feed a small handful of outlets and lights in each room. All the rooms except for the bathroom have one light in the center of the ceiling, and two outlets in each room. That is all that is in the 4 bedrooms on the third floor.

This all has been replaced with a 100 amp sub-panel that is located on that floor in a closet. I have added lights and many more outlets per room. Each room has 14 outlets(2 distinct circuits) in the baseboard and two lighting circuits. I like to have multiple circuits for outlets in each room. And I keep the lights and outlets on separate circuits always.

I have attached a copy of the picture of the original circuit panel that used to feed the entire 3rd floor.
