40mm bofors 40/60

picked up a 40mm bofors casing today and need help dating it. Head stampings outer band; EAS 10 A 600S001 EAS 09 G 003-002 40/60
inner band; LOT EAS 09 M 004-001 M80

As a general rule lot codes are as follows (FM 9-13 Ammunition Handbook, Appendix D,1986 Ammunition Markings, Lot Codes, Designations]):

EAS in the Ammunition Manufacturers & Symbols 1999 MIL-HDBK-1461A = ENGINEERED AIR SYSTEMS INC., ST LOUIS, MO which may not fit here.

The only other EAS I can come up with is Hellenic Defense Systems S.A. (ΕΒΟ-PYRKAL) or EAS, Athens, Greece which produces ammunition. They were producing the 40 mm L70 Bofors ammunition in 2012 but I don’t know about the 40 mm L60 Bofors.

Hopefully someone else can help with “EAS”.


Brian, as per their website they still offer 40/L60 rounds:


I figured you would look in.

Thanks for the link.


Now it happened - I became predictable!
