Vintage Bausch And Lomb Tessar Lens

Here is a very old lens which I assume would have been an enlarging lens. Serial number3246976 3 5/8' F/4.5 TESSAR I C  , 2/14 /3 1/4 which tells me it covers that size negative. The iris is smooth and the glass is pretty outside, BUT, the inside I easily see fungus on the elements. Still, if you can clean this lens, this is a very old lens and looks good on the outside with the packaging as it came from the factory. This was obviously a new lens when I got it from the Burke and J...ames lens factory when I purchased the remaining inventory back in the late 70's but it was not stored in my vault like most of my treasures and this one picked up some moisture thru the years. Again, the fungus is easily seen and buy it accordingly.
