Stefan, I can sell you one of the Sarco/Numrich unnumbered repro extractors for $25 + $3 S&H or some better made DDR replacements for $40 or numbered (even the commericals were numbered on the inside; militaries on the outside) @$50. Perhaps the one on ebay was a factory marked, but unnumbered armour's spare. I sell these for $75.
