Hi fellow collectors, A few days ago I got this stove from Czech republic. It is very special because it has two separate spirit reservoirs for pre heating and for running the stove. The pump has two valves, one is connected to a tube that pressurizes the small reservoir separately. Once pressurized you have to open the red handle to fill the pre heating dish. The black handle on the left is the pump. I will take some photos once restored. The following photos are courtesy of the seller.
