Vintage 9" J. C. Mills Pies Company Tin Indianapolis, Indiana Cooking Baking

Description

I recently found several of these J.C. MILLS PIES COMPANY 9" PIE TINS in Columbus, Indiana. I could not find much information about the company besides a few mentions in obituaries, but I believe it was around Indianapolis.  If you have any info and care to share I would love some history.
All tins are in excellent used condition with some scratches and minor surface rust on the rims. A few of them probably were never used and the imperfections occured due to bad storage.
