refinished single-sided diminutive cast iron number plaques salvaged from an a. finkl & sons foundry overhead crane likely fabricated in the 1920's or early 1930's. the brushed metal numbers likely reflect the identification number for this particular crane used for decades. the group of numbers are housed in their original heavy gauge steel steel sleeve that was bolted against a large steel plate that also contained the manufacturer's name plaque. the entire informational plaque was removed from the overhead crane shortly before it was brought down and scrapped. the manufacturer name plaque is available in a separate listing. the brushed metal finish has been sealed with a clear coat lacquer.
