    The 1925 Primus No.4 marks the end of this particular burner type. This burner has a fixed outer burner ring with removable cap and no holes punched in the base of the burner dish, both of which are present from 1926.

    More on the restoration in the post Project No. 4

    and the overheating problem solved in the post How hot is your burner?

    The brownish finish on the pot stands, is it paint?

    The pot stands had suffered quite badly and I re- zinc coated them. They are actually a silver-grey colour.

    Did you give them hot galvanization, or just cold spray of zinc paint?

    I didn't want to desolder them for hot dipping so I used "CRC Zinc It" Time will tell how robust it is. So far I've noted that it seems to be heat proof, not degrading in the flame area.
