This is a brief history of jerrycans with the addition of a few design details. It’s really dry reading, and it’s long, so fair warning. In fact, just skip it.
The NATO fuel can has a long history. It was invented in Germany in the late 1930’s and was used extensively in WWII. It was referred to by the allies as a “Gerry can”, Gerry being a mildly pejorative term for Germans at the time. Somehow it has morphed into Jerrycan, but I don't know when or why. After the war the German Jerrycan was adopted as the NATO standard (along with the 9mm Luger round.)
My first 4WD vehicle was a 1985 Toyota Extra-cab pickup. At first I had a few plastic cans, but they didn’t last very long. I was considering getting a couple of Blitz cans. That’s what all the Jeep guys were carrying at the time. But I had heard some bad things about them.
All three styles of containers, the Wavian, Blitz, and Sceptre, share the characteristic triple carry handle, which allows the can to be carried by two men, or 4 empty cans to be carried by one man, or for cans to be passed man-to-man down a line. All three also are designed with an air space at the top to allow for thermal expansion. They are all roughly the same size and capacity. That’s where the similarity ends.
The Blitz cans routinely leaked. It was hard to achieve a reliable seal on the cap, even using a tool to tighten it. The construction of the can used a rolled seam around the bottom which was prone to rust and would split as a result of rough handling. By comparison the NATO can had a longitudinal seam that was welded rather than rolled. The seam was recessed as well. The recess protected the seam from impacts and moisture. The cam-lock lid has the advantage of merely compressing the gasket, rather than compressing and distorting the gasket with a twisting motion as with the Blitz and Sceptre containers.
So then one day at the surplus store I saw the NATO jerrycan. I bought a pair for $15 each, replaced the gaskets with new ones, and never looked back. I was lucky to find them because not very long afterwards the supply dwindled and pristine copies became rare and expensive. After almost 40 years those two surplus cans are perfectly serviceable. They don’t leak. No liquid. No vapor. Nothing. I took them on many adventures and slept with them in the covered bed of my pickup and never smelled a whiff of fuel. They can be laid on their backs or on their sides. No leaks.
Several years later, after a sizable earthquake and a days-long power outage, I decided I needed more fuel storage capacity, so I bit the bullet and sprung for another pair of jerrycans. By this time only re-enactors we’re shelling out the huge prices for original Wehrmacht cans. So I bought “re-pops” from Wedco. Wedco was only an importer, and the cans were made in Latvia by a manufacturer called Valpro which took over manufacture of the cans after the war. The Valpro cans are a faithful, if not exact reproduction. The Wavian cans available today are made in the same facility as the Wedco cans were, and are identical in every respect except for a brand stamping on the side. The Wavian/Wedco/Valpro cans use a lighter gauge sheet metal than the original German version. In spite of that difference they still meet the NATO specification. I have 10 cans now (some are 10 liter and some are 5 liter). They have been continuously stored full for years.

Next:OG and Valpro NATO-style cans, the Blitz can, and the military version of the Sceptre can.
Next: 4 photos of the Wavian/Valpro can, with details of the cam-lock lid. Note the stamping of the date on the hinge. Also note the detail of the recessed welded seam.
Finally: Valpro and Wavian logo stampings.
Epilogue: Sceptre is the Glock of jerrycans. Wavian is the SIG Sauer. Sceptre dint replace Wavian because it was an improvement. Sceptre replaced Wavian because it was the low bid.
