Waterman, the Marble Goss is surely the best sight you can put on a 54, but I can't gat to it, whold apardtment is being rebujilt and I am in Mexico. Steev, I looked in the midrror, no scar on my nose any more- was probably sixty yeaars ago. Just for info, Joe Goss wasa a amllbore guy and the sightsd, for 52s, show up frequently on ebay.
