Some parts are chrome over steel, some chrome over brass. There is pot metal as well. I just put a magnet to headlight benzels which are chrome plated. It non magnetic so probably pot metal.
I suggest you post this question on the sl113.org website. Many members more knowledgeable than me. Stainless steel, as for whether they are magnetic, the answer is that it depends. There are several families of stainless steels with different physical properties. A basic stainless steel has a 'ferritic' structure and is magnetic. These are formed from the addition of chromium and can be hardened through the addition of carbon (making them 'martensitic') and are often used in cutlery. However, the most common stainless steels are 'austenitic' - these have a higher chromium content and nickel is also added. It is the nickel which modifies the physical structure of the steel and makes it non-magnetic.
