1965 18J6 Steel Joist Capacity 1

[thinkhard]

I'm working on a building constructed in 1965 that has 18J6 steel joists spanning 27 feet. Does anyone have a table from that time-frame that indicates what the capacity of the joist is?

Thanks SlideRuleEra. I actually have already ordered it but it hasn't arrived yet and I was hoping to keep moving forward if someone will help me out.
