For your inspection today is my second non-Coleman suitcase stove, an AGM WCS3. "The best camp stove money can buy." Pure marketing, of course. Overview of case. The photo does justice to the outside, what it doesn't show about the inside is that many areas were sticky and greasy with someone's bacon sarnie leftovers. Rear label once windscreen wings were folded out of the way. Slash across is mostly icky grease, not rust. Pump/filler cap removed, overview. The grey/gray section is actually painted or plated brass, not aluminum. Pump rod screws down. I didn't see a seal anywhere but I think this is a very rudimentary version of Coleman's locking pump. Pump leather was intact but bone dry. Pump leather oiled and reinserted, the pump worked beautifully and pressurized the tank just fine. Soapy water sprayed on the works, with pump handle screwed down it seems to hold pressure just fine. What about without the pump handle screwed down? That won't do! Time to have a look at the NRV. Tight grip with a rubber work glove on the pump tube and an adjustable spanner on the NRV nut got it loose. Here's a view of the NRV seat: To be continued, next post.
