Cast Iron steel plate Oskaloosa Iowa

[drishoff]

Any input on this 3/4"x 2'x 4' steel plate with Iowa mfg & Oskaloosa marked on it with decoration and Iowa state outline? Where and when were these type of advertising things made?

Hello drishoff,

Welcome to TNet. What you have is quite literally "boiler plate."

Iowa Manufacturing made, distributed & serviced boilers & incinerators in early 20th Century Oskaloosa. See the multiple listings for them in this 1915 Engineering Directory.

Is that your Craigslist Iowa steel mfg history informational inquiry?
