>From the AISC text "Iron and Steel Beams: 1873 to 1952", the closest that
I found is:
tf (at tip)= .35"
A=12.41 sq. in.
Note: the properties for the above shape are for a section produced around
1907. There are several (10+) other sections that are VERY close but this
one best matched the dimensions that you provided. The section props are
very similar for hte other beams (most had webs that were about .300").
If you know that date that the original building was constructed, I might
be able to be a little more conclusive.
Hope this helps,
