Historic I-Beam Information

[Toby43]

Hi all,
Anyone have any data on historic I-beam shapes use in Australia (specifically WA). I am assessing an existing building which has a 360 deep I-beam with a flange width of 140mm which doesn't match todays profiles. Building is circa 1950-60. I'm specifically chasing the steel properties (yield etc...).

Thanks in advance
Toby
