Vietnam-Era Training Poster Identification Of Hand Grenades.. Very Hard to Find!

Description

Without a doubt, this a super rare training poster “Identification Of Hand Grenades”
There is a (production code?) at the bottom right, but Searching turned up nothing… AE GTA 9-043
At first I thought the “043” meant 1943, and WWII. But the grenades are post WWII….and entered service during The Vietnam Era.
There may be another one somewhere, but I haven’t seen it on the Web, and I want to say it’s pretty close to being ‘one of a kind’ Regardless, It will be a terrific addition to your collection!
CONDITION: there are 2 rips at the bottom, about 8” long. The ripped edges line up. I don’t want to alter it. I do believe if you want to, repairing with (archival paper tissue, or repair tape), would work well.
Edges have some light fraying. Overall the colors are good.. the photos are NOT altered.
Display As-is or repair, it’s an amazing poster (that brings back memories of my Infantry training 40 years ago!)
Measures about 34” x 44”
Ships rolled and gently secured.
