The Egyptian vertical pattern was first created in 1971 for export (source: https://www.camopedia.org/index.php?title=Egypt). The pattern is very similar to other vertical lizard patterns used by Syria, Lebanon, and Libya at the time. The SADF Recces also produced a copy of this pattern, Copy J.
In the 1980’s, some Egyptian troops wore the same pattern, but in a darker green color.

Sample 1:
Lighter color, sparse region is probably an artifact of printing. It appears in other panels of the garment. This shirt was recovered at the Guineafowl School assembly point in Gwelo (now Gweru, information provided by seller), along with the Strichtarn and Korean shirts. Like many insurgent-used items, it shows signs of heavy use.
Tag Remnant:
Long tag would have been here.
Pockets:
Simple open top pockets with button closure. A small fabric scrap was found inside the left pocket (as worn).
Cuffs:
Unlike its SADF exact copy, the cuffs do not have any adjustment buttons.
Epaulettes:
Collar is in two pieces.
Inside:
Internal pocket under right side (as worn).
Sample 2:
Same as above, but with an intact tag and added arm pocket. The faded “stripe” misprint also appears to be horizontal on this one.
Tag:
Egyptian manufacturer.
Arm Pocket:
Likely field tailored since it looks hand-stitched with different thread than what was used on the rest of the shirt. The thread appears to be synthetic, maybe something like fishing line or dental floss?
