Al, In addition to having one of these spare unnumbered DDR rear links with the 90d knurling & uncut tops in stock, I've also seen them on several DDR reworks and on the new DDR "N" prefix production PO8s. According to Costanzo's "Proofmarks" page 195, the C/G proof indicates repair by Simson if it has a 5 pip crown and Mauser, if 4 pips are used. TH
