Okay...now I am really confused...
Per the photos on e-Bay, this is a type "B-2-B" magazine; using the Gibson jargon (i.e. fxo code, blue extruded, with P-08 and E37 stampings. Per page 56 of Gibson's book, this magazine should have a full serial number on the bottom with an up-side-down LWaA 1st, Stage 1, Early proof stamp above the serial number.
But this magazine seems to have a LWaA 1st, Stage 1, Late proof stamp that is right-side-up...which Gibson mentions rarely occurs on some type "B-2-D" magzines (i.e. 122 code)...but this is not a type B-2-D magazine...
