Looks to be commensurate with the age of the building. Other clues are smooth planed dimensional lumber multiply sistered together to make an adequate joist, along with that flexible metallic conduit and black iron pipe. I've seen the same materials used in homes from the late forties to mid-fifties. Am I close?

Clearly then, the rather limited section you've photographed is certainly not original to a home built in 1870. Can you disclose the point of your inquiry?.. Are you concerned with the reliability or current capacity of that particular large gauge 3 conductor jacketed wire?..

Also a home inspection site about cloth covered wire. http://www.mystpetersburghomeinspect...ed-wiring.html discusses use dates and notes how brittle the insulation has become since use.
