The smaller 442 was made from smooth aluminum sheet, while the 443 features dimpled aluminum. This stove also has it original aluminum legs which often go missing. So to find one in this condition is quite rare.
This stove has not been refurbished in anyway. Its not NOS, but I would say its close to museum quality.
