Hi Herschel,
On the other hand this lens has a mounting ring with it with a fine thread ...
not a Leica thread. It leads me to believe it was intended for attachment to a
board of some kind like on a view camera ... not likely the front standard of a
35mm or 2 1/4 bellows. Besides, it is a 150 or so mm fl lens ... when operating
in the 1:1 range the lens to image distance would be about 300 mm ... probably
enough t cover an 8x10 ... or 8.5 x 11 format paper. The MACRO designation is
"worrisome" I agree.
cheers,
andy

Companies like Novaflex made bellows with a threaded lens panel. I know that pentax screw mount lenses were around 42mm and I think Leica screw mount was 30something mm.
1. Large format lenses generally have shutters (Sinar make a shutter that replaces these)
2 I have never heard of a large format lens engraved "Macro".

It could be a copy lens ... maybe designed for Haloid or Xerox copiers which
were made in Rochester ... which is where B&L is also. Probably for 1:1 copying
but possibly from their larger format copiers. It has a diaphragm built in. That
is good.

Without an integrated shutter built into the lens, it probably isn't a
large-format lens. I'm thinking binoculars. Anyway, there are certainly
ways to get it to fit your 35-mm camera; creativity helps.
