Hi Glenn,
* Hope the attached link(s) help explain the E.C.C.S.A Importer's mark on your Luger.

* FWIW: I also have run across an AutoMag report indicating E.C.C.S.A. stands for "East Coast Combat Shooter's Assoc." which was owned by the same fellow who owned the Cross Roads Gun Shop in Pensauken.
Respectfully,
Bob
