Eastern Railroad Discussion > Info in Chicago area

Hello Chicago RR Fans,
I'm looking for info on a LASSIG BRIDGE AND IRON WORKS Company. I have
a plaque from a steel RR bridge that was built by this company in Chicago, ILL. in 1899. I have tried the yellow pages with no luck. Does anybody have any info on this company. Did they fold up, bought
by another company or what? I would like to find out what color this plaque was painted in order to restore it and then give it to our Muesum to display in our Depot. This bridge was on the Kansas Pacific Line
across Kansas. Any help on this would be greatly appreciated. Thank you in advance. upkpfan
