I have had a dig through the many wonderful photos of board member's Curtas, and I know that the subject of this thread is already available deep in the content here, but I would like to request that someone post a few clear comparison photos from suitable perspectives that provide a quick photo reference guide to metal vs plastic cranks & clearing rings on assembled Curtas.

They're the same for Type 1 and Type 2. I know, I had a couple of hundred made (let me know if you want to buy one). They fit both types
