Stainless steel material, Gold tin. High performance iambic paddle with magnetic return.
It has gold contacts made from massive 14K gold.
The key is in perfect condition. Was bought in Dayton from Begali. It signed by Piero, I2RTF. Used for 3 weeks only.

I can easily crush along with 45 wpm during my QSOs or CW contests. Few keys in the world will allow sustained operation at these speeds without fatigue.
It is like Ferrari among cars…
