Diana 23 piston seal ? any one have info where to buy one , i think the 23 i have just blew the seal ? was just shooting and suddenly now there is a metal ping sound i think is the piston slam ?
if my looking tells me anything it might have a leather seal Knibb has them but that was just a quick look if you thing it is broken you are going to have to take it apart and if you can't these old 23's have very little value JG air guns has parts just take it apart see what you need and find the parts
