Cobbler1,
I looked at your gallery. I bought one of those tools in your first image. A couple years I looked around in southern Georgia and found several in antique stores for between $15 and $40 bucks.
That German sign is for a sewing machine company.
I found online: On Tuesday, November 15, 1955, a U.S. federal trademark registration was filed for ABC. This trademark is owned by KOCHS ADLERNAHMASCHINEN WERKE A. G., BIELEFELD , . Trademarkia.com is a free search engine of publicly available government records.
Vintage German Adler Cl. 87 Sewing Machine (Kochs Adlernahmaschinen Werke A.-G.). Comes with original latching box, instruction manual, but no foot pedal. Appears to be in pretty good shape, with little to no rust or wear. I'm not certain that it's works, as it might need the foot pedal to activate, but it seems pretty good overall. It is very, very heavy. Serial number on metal plate under the needle says "1932." Appears to be the same model listed here: https://usa-dealer.3dcartstores.com/ADLER-87_p_1444.html $300 or best offer
