There is a perception that in the 60's and 70's backpackers carried horrendous loads. That is not truly accurate. Although it was not uncommon for backpackers to carry enough food to last for 10 – 14 days, and that makes for a heavy pack. But there is something to be said about the wilderness experience that limits your exposure to town to just once every two weeks.
If one were to look at base weights "back in the day," it would not be uncommon to see sub 20 lbs kits, which by today's definition would be "light weight."
When I got out of the military in 1971 I went directly to the Sierras for 6 months. I bought some new gear, and also used some military stuff. One of the military items was a canteen stove, mostly because I did not know there was such a thing as a backpacking stove. In 1972 I bought a Svea 123, which pretty much was my main stove for a long time. However, I occassionally brought the canteen stove on some trips. The stove could use Esbit, Trioxane (military fuel similar to Esbit), wood, and even alcohol. In 1971 I found it nearly impossible to locate Esbit or Trioxane. Here are some pictures and explanations.

Stove, cup, and canteen fit into an insulated nylon cover that could be attached to the hip belt. There is also a little pouch that could store a bottle of iodine tablets, my main purification method until 2009. After about a month I sent the cover home.

Canteen, cup, and stove nest into a single package.

Canteen, cup and stove. The cup holds 20 oz. Normally I would boil 12 – 16 oz. There is not lid, and I used aluminum foil.

My original cup is made from steel. Sometime in the early 70's the military switched to aluminum cups with a butterfly handle.

Something like a Succrets or Altoid tin can can be used to place an Esbit tab (the smaller one). If you fill it with dirt or sand, you can then fill it with alcohol to boil water. It burns too quickly without a filler. A Pepsi can is too high to work. If you keep both halves of the tin, you have a small storage unit for multiple use. But this is a nice "off the shelf" system, and you can probably buy a used set-up at a surplus store for under $20, maybe under $10.
Here are the weights:
Canteen = 5.5 oz
Stove = 1.75 oz
Steel Cup = 8.38 oz
Aluminum Cup = 8.00 oz
In 1971 I usually used this set-up for breakfast. Since I often had trout for dinner, I brought a military mess kit and spoon. Eventually I sent the top half of the kit home (plate) and then bought a larger pot to cook over fires.

Pot and lid = 5.75 oz
Fry pan = 8.75 oz
Spoon 1.52 oz
