I just acquired a nice new englander 54 caliber. I actually purchased it for 100 bucks for the stock for my 12 gauge barrel. However the barrel is is such nice shape, I plan to keep it and use it. Anyway It had a williams sight on the rear and the partridge one for the front site. The only part of the site left was just the base. I was thinking of a tang receiver site, but since the stock will be used for my 50 and 54 caliber barrrels, it will not work, and they are impossible to find. So, I was wondering if Williams a receiver site I could put on the barrel where the old site was? If so does anyone know the part number? Thank you in advance. I will get one for my 50 and 54 barrels.
