This antique brass Steinheil in Munchen No. 15175 14'' (355mm) large format barrel lens comes with its mounting ring. It is 2 3/4'' long by 3 1/2'' wide and its mounting ring is 4''. There is discoloration and a few scuffs and scratches on its exterior. Its rear element has some kind of spotting on it. We unsuccessfully tried to clean the spots off with lens cleaner. Likely won't make a bit of difference shooting with it. Its glass is free of any haze, fungus, or separation to its elements. Waterhouse stops not included. Will cover 8x10".
