Here are a few pictures of the Himalaya Series, from the top in the order of appearance, Omni Fuel, Multi fuel EX, and Multi Fuel. The new Multi Fuel EX sports the newly designed burner that works as well as that of Omni. The only difference in the operation is its simmering capability is slightly reduced. It will still simmer quite well, but the flame becomes unstable, if brought down to a certain level. This is caused by the lack of additional control valve that Omni is equipped. In the picture, Both Omni and Multi EX are burning white gas, while old Multi is burning kerosene. Because the Multi's burner is Stainless Steel, it glows brightly. Omni and Multi EX have brass burner. Also note the improvement on the pump. The one on Multi EX has bigger knob and brass fitting. Omni and old Multi has the identical pump. The Multi EX's fuel line and the connector to the lindal valve have been reduced in the diameter and weight. The flame patterns of Omni and Multi EX are the same, and in performance, there is no distinction.
So which pump do you like better? I have one of the old non-ex multifuels that i picked up a couple of years back. I really like the tilt on the ergo pump that saves you from scraping your knuckles. That said I generally prefer a metal pump in case of fire. (unintended fire)
I actully do like them both, although the new one has the "ergo" factor. As you say, I like the fact that the old one is all metal! Heavy duty!
One more thing that I've noticed about mine... The older style MF emits quite a lot of light from all the glowy bits... Not so much cherry red... Pumpkin orange!!!
Some info from primus about the pricker size for the omnifuel... "The diameter was 0.23mm until 2008 when we changed to 0.20 mm As your OmniFuel has 0.28mm jet for kerosene you can have up to that diameter maximum." Dan
I'm not sure if bark2much meant in order of appearance in his photo's or when the stoves appeared but according to the Primus Time Line, the Himalaya Multi-fuel debuted in 1997, then the Omni-Fuel is launched in 2001. The Multi-Fuel Ex was based off of the Omni and I've never seen one with the Himalaya style body. Also technically there are only 2 Himalaya's by name, the Multi-fuel and the Vari-Fuel. While the early Omni-Fuel and 3277 LPS shared the Himalaya stove body they were never called Himalaya's.
Both the Omnifuel and the Easyfuel was also called Himalaya in the name. So there was 5 + the mesh lantern. This is how it looked like on www.primus.se back in 2002: https://web.archive.org/web/20020203073648/http://www.primus.se:80/konsument/as_himalaya_e.htm

@HunterStovie @afoton I know nothing about the Himalaya stoves, apart from what I have read on CCS. I thought that my links to CCS paperwork would have got some comment from you. I feel sure that both of you know a lot more about the topic than me.
@afoton @shagratork I've been on vacation in northern California so I could not respond. Thanks for the above link. I have an Omni-fuel dated 18 / 03 / 2003 that came with the metal pump and old style thick fuel line so I know it's original but the is no reference to "Himalaya" on the box or in the instructions, hence my comment. If the stove was actually sold with the Himalaya name on it, at least in 2002, I'd like to see it. Also I'm not disputing the MF or VF just the Omni. The box matches the specs for 8000 btu's which I thought odd since it contains the same jets that come with all Omni-fuels. The 3277 which I have says LPS in the instructions, I don't have the box to verify any labeling. The Easy-fuel II looks similar but again not called a Himalaya I ran into a similar problem with the Primus Lander as it was advertised as VF but does not mention VF on the box or in the instructions which means they eventually changed the name after the announcement.
