Bethelem 27 inch section 1

[wooddesigner]

I have 27 inch deep by 6 inch wide flange by 0.5" thick web I I beams by Bethlehem. They do appear to be in the AISC historical sections catalogue. May be a special crane section. Anyone have a source for the properties?

Correction and request withdrawn. It is an 18Ix54.7. Field notes were blurred due to being 30 feet in the air. My apologies.
