Monday’s item of in is this very nice Luftwaffe blue/grey carrying case for 12 3.7cm Sprgr. Patr 18 Flak gun shells. Complete with its shell rack and securing bar. It also has a very nice label. The feldpost number ( Fp 26769) refers back to a Luftwaffe Munition camp which is a nice addition.
These carrying cases are particularly hard to find with the racks in place as they made it almost unusable for any post war use and were normally removed to allow more storage room.
I will start to fill it up with any cases with heads that I have, and it will look quite impressive when done.

Below is some information from the internet on the ammunition that this case would have contained. Hopefully this will be of further interest.
The 3.7 cm Sprgr. Patr. 18 (Sprenggranatpatrone 18) was a standard high-explosive (HE) fixed ammunition round utilized by the German military during World War II. It was primarily fired from anti-aircraft and anti-tank guns such as the 3.7 cm FlaK 18, 37, 43, and the 3.7 cm PaK 36.

Ammunition Breakdown:
The Patrone (complete round) was a fixed-cartridge design, meaning the projectile was crimped to a brass or steel cartridge case containing the propelling charge.
The "Sprgr." designation stands for Sprenggranate (high-explosive shell). It typically featured a tracer in the base of the projectile (often denoted as L'spur or L'Spur) to assist with anti-aircraft targeting and trajectory correction.
