Thanks for the storm of ideas, Bernd. It looks like this one will take some more time and expertise. I wonder if John Kashuba might shed some light on (through) this TS? What are some other ideas for the notations on the bottom label? 'Ct' could be an old abbreviation for county, which would point to Homestead, though it is typically 'Co.' It would seem odd to abbreviate a short word like city. Perhaps the '61' and 1861 are a coincidence and the 61 is simply the number assigned to that slide.
Fun stuff!

Meteorite Thin Section A few ideas after brainstorming a bit ... what brain? :-) Mike B. writes: " Iowa has three official chondrites to its name prior to his passing. Marion, 1847 (L6), Homestead, 1875 (L5) and Forest City, 1895 (H5)" *If* it's Marion, you might find veins because Marion is described as having veins. *If* it's Homestead, it should be brecciated and severely shocked (S4). *If* it's Forest City, it should also show brecciation. Hmm, Homestead and Forest City, ... both brecciated :-( But: Measuring the diameters of the chondrules might help here as Forest City chondrules (H5) should be smaller than Homestead chondrules (L5). By the way, just in case your thin section should contain copper, ... Homestead is described as containing copper.
