Hello,
if anyone is interested I have a few pieces of clearing levers for Curta I and II cut from stainless steel.

In the picture on the left is the first removable version (stainless steel thickness 2mm, for Curta I and II), the second is a modified original (wider finger ring, stainless steel thickness 1.5 mm) and the third is according to the original (stainless steel thickness 1.5 mm)

If anyone is interested send me a PM

Thanks
