For maybe the one or two members who really don't yet know, every one of these Leica copies -- the Tower, which is the Sears name for the Nicca, the American-made Kardon, the British-made Reid and other leading Leica copies [the Canon, the Honor, the Leotax, the US-made Ektra, the Chiyoca and others] are all very fine [and expensive] rangefinder cameras...
The Reid III is a copy of the Leica IIIb, according to "Leica Copies," by HPR, and the Reid I is a copy of the Leica Standard...Early ones were made for the British Army and have Army markings...They all came with the excellent British-made 2 inch, f/2 Taylor, Taylor & Hobson lens... It"s as nice as a Leica and in that price class.
The hardest to find are the Kardon and Ektra but my favorite -- if I can find one some day -- is the Japanese-made Honor. Years ago I turned down a chance to buy one for $50 usd because I'd never heard of it...I bought the case for $5 but it disappeared over the years; it's probably worth a lot today because Honor cases are very rare...
I do have a couple of Tower/Niccas -- including the Tower 45, which is the Nicca 5, with the lever wind and horizontal back door, like the Leica M3...
