Here's my Petrolamp 200 made in Italy. Nothing special to do, only a good cleaning and replace the old seals.
@Johan Osinga Were there any markings on the valve casting? Neil’s Pressure Lamp Catalogue has Petrolamp as: “Petrolamp Italy ?? 250cp as Petromax 821. Alcohol pre heat only. All nickel plate… . Valve body casting embossed with “Petrolamp Made in Italy” Logo of P in a double circle on filler cap. Cheers Tony
@Tony Press , There are markings on the hood, as you can see in the pictures, Petrolamp 200 made in Italy. On the bottom of the vapouriser is also stamped "Petrolamp" on one side, and the other side " made in Italy". The bottom of the fuel tank is ribbed, like Neil's Petroflam . And you can also the "P" on the filler cap in the double circuleren. The globe is marked with "pyrex"
