Help ! Disassembling my Parker 51 double Jewel in black , and managed to crack the barrel . Does anyone possibly have a spare barrel . The one I have is marketd *6* so I assume 1946 . I may try to fill the crack , it's along the barrel and is about 2 " , although I don't hold out much hope , and would love to get it working again . Devastated !! What an idiot !! I'm sure there must be plenty of spare parts out there ? U.K. Based here .
