I got my old Slavia 618 out last week and was amazed that it still shoots hard after 50 years! I bought the gun about 1957 at the Army Navy surplus store for $8.00. I was king of the hill as the gun shot harder and more accurately than the neighborhood Daisy BB guns which were numerous. Over the years the sights have broken. Any idea where I could find a rear sight for this gun? It has a dovetail for the rear sight and the front sight has broken off years ago. It is not worth fixing moneywise but for me it would be nice to have it in original shape again.
