The actual mount is 36.4mm at its narrow base and 36.6mm at the widest part of the thread. Though the Summitar was introduced in 1940, the filters were not catalogued until after the War ended, though I suspect that they were probably available by special order. Laney states that they were introduced in 1939, but they do not appear in the 1940 photographic catalogue either in Germany or the US. I probably should set aside my book on Kilfitt and Zoomar and knock out a monograph on non-digital Leitz and Leica filters, including mind-numbing charts running to page after page of fine print! I have never made a special effort to acquire Leitz filters but I have ended up with a bunch, though my holdings are just a drop in the bucket given the huge range of such filters produced by Wetzlar and ELNY. In any event, here is the best listing I can produce for the Summitar filters. These were known at Wetzlar as L filters (by comparison, the E39 range were O filters). I suspect there are more out there which haven't yet come to light as they probably were never catalogued. Very Light Yellow GBOOM 13080 Light Yellow GBWOO 13085 Medium Yellow GCOOL Green #1 GEYOO Green #2 GCYOO 13095 Graduated Yellow GHOOF 13105 Graduated Green GILOO Orange GDOOK 13100 Light Red/IR GECOO 13115 Medium Red/IR GFEOO 13120 Dark Red/IR GFOOH 13125 Blue RQPOO 13097 UVa GHIOO 13130 Blank Filter Holder FOOXC Haze FIHAZ Skylight GCSKY 13150 Type F FKDSUM 13137 Type FP FPKSUM 13147 Type A FIDAY 13135 Photoflood FIFLO 13140 Flash Conversion GCHEO 13145 Swing-Out Polarizer FISUM 13395 Rotating Polarizer POORE 13355 Filters which only have a catalogue code-word and not a catalogue number did not survive into production to 1954, the first year for the universal use of the numbers. Many of the Summitar filters had dropped out of the catalogues by 1960 and all were gone from the Leitz catalogue by 1962. Both Tiffen and Ednalite supplied Series VI adapters in the L mount; I got an early Tiffen one with my IIIc and have used it extensively, often just as a lens hood and without a filter. I forget the Tiffen part number but the Ednalite adapter was their number 601 and these are relatively common. I have one such new-in-box for sale which I could not find but we are throwing a neighborhood yard sale tomorrow and I shall have most of my camera surplus out there and I shall see if I can find it. I have a UVa and Very Light Yellow filter in early boxes (pre-1954 and could be wartime) and #2 Yellow, #2 Green, and Dark Red unboxed. I got these from a variety of sources but I don't believe that any cost me more than $0.50, and the two boxed ones were a gift from a member of the LUG eight or ten years ago. Ask folks. Look on eBay -- search by the Codeword to see if some idiot lists a GBOOM as "unknown Yellow filter" or the like. But, again, I use my Tiffen Series VI adapter on my own Summitar as a lens shade and when I do use filters, I use H&H Series VI filters. Folks, the next lecture willl be at 8 O'Clock tomorrow evening in the Berek Auditorium at Kellner Hall. The topic will be, "Bayonet Filters for the Leitz Xenon and Summitar Lenses". Take notes, as there will be a test at the end of the lecture. AND TURN THOSE BLOODY CELL-PHONES OFF! Marc msmall@aya.yale.edu Cha robh b?s fir gun ghr?s fir!
