I didn't take a picture because I'm an idiot - Odd Singer at Goodwill in TN
Black like a 66, electric belted motor mounted on a motor boss, No model number, emblem low on the pillar, solid brass in color, Stitch length above the emblem, The selector plate was black. The face plate was plain with no scroll work or striations. Above the stitch length plate and lever was a Zig Zag or needle position selector almost like the one on a Bernina 117 but not as fancy; maybe only 4 positions. It had an oscillating hook and the bobbin was included. The throat plate didn't slide off and it was oriented opposite the bobbin - the bobbin was a front loader but the throat plate looked like the bobbin would be a side load like a featherweight. No serial number was visible and it was too heavy for me to get it off the floor to flip it over. It was at the Cookeville, TN Goodwill on Sunday at 4:00pm.
What it is not is a 206, 306 or 319.
I have never seen a Singer machine like it.
