"Tower" was a house-brand name used by Sears for cameras they'd purchase from a number of OEMs. This particular one looks very similar to the Argus V-100, except with a top-mounted instead of front-mounted shutter release. I used to know what German contract manufacturer made the V-100, but that information has escaped from its memory cell.
The V-100 had a good lens and shutter, but the body was a bit cheesy and operation was semi-quirky. If I recall correctly, it had one of those rapid advance levers built into the "shoulder" of the camera, rather than on top, and you removed the back by lifting the rewind knob past an interlock and turning it in the opposite-to-normal direction; this would cause the back to pop completely off under spring pressure!
The bottom camera looks like a "Match-Matic" C3, an otherwise-standard version of the Argus C3 except for its light leatherette and the fact that the knobs were marked with symbols for use with a shoe-mounted selenium meter that came with it. The idea was that the match-matic symbols would make it easier to set than standard f/stops and shutter speeds (although it was marked with these, too.) I don't think the idea ever particularly caught on, but it did yield an, er, distinctive-looking camera -- perfect for carrying when you're wearing your white buck shoes and plaid madras pants!
