Burner - Metal, Cast iron, steel, brass - Max Sievert Aequator No 6

Rare attic find from Sweden: antique Max Sievert Aequator No. 6 soldering oven or casting pan, produced in Stockholm, Sweden, in the early 20th century.
Function: It was used as a portable stove or oven, often for melting solder tin in telegraph and telephone work.

Material: The construction consists of a copper or brass base with a cast-iron housing and pan.
Features: It is a heavy, industrial tool; its operation is unknown, not tested, and I don’t know if it is 100% complete.
Because I myself don’t know how it works, it is an attic find from Sweden.
