Old Steel Girder Properties / Dimensions 1

[MRJR33]

I am working on a existing bridge that was built in 1934 and is 2 hours away from our office.
The old bridge plans show the wide flange steel girders were WF24x80.
The oldest steel manual I have is from 1960 (5th Edition) and the WF24x80 was not in production at that time.
Is there a website containing old WF beam properties and dimensions or do I have a 4 hour drive?

It is not listed in the 1949 Edition, but is in the 1934 Edition of the AISC Steel Construction Manual, pages 16 ande 17.

It is listed as a 24 X 9 WF section with the following properties:

A = 23.54
d = 24
bf = 9
tf = .727
Tw = .455
Ix = 2229.7
Sx = 185.8
rx = 9.73
Iy = 82.4
Sy = 18.3
ry = 1.87

On page 225 (Standard Specifications and Codes), it references ASTM A7-33T under Specifications for Steel for Bridges.
