My Leica is chrome... is there an appropriate tape to blend with this finish? 🙂 Actually, as an M2, it only says "Leica' on the top surface, and this is not so obvious to others. I haven't done any taping, but I can sympathize with the idea, if only to eliminate the "Oh, wow, a Leica!" response from those who have heard it's the greatest and want to exclaim over it.
I had the same kind of annoying attention in 1970 with a new Honda 750-4... the only 4-cyl m/c on the market, new, unusual, fast, and flashy, and folks were always asking me how fast I'd had it up to. Really no way to disguise the thing, though the subdued blue-green color might have helped a bit. A relief, really, when the Kawasaki 903 came along and mine was no longer the only 4 and fastest thing on 2 wheels. 🙂
If I had a black M with white lettering and red dot on the front I too might be tempted to tone it down a bit just in the interests of discretion. Hmm, I guess I could do that with the Zeiss Ikon, (unlike the Minolta CLE) another "wow" brand!
