Hi,

I recently purchased a Curta Type 1 on ebay.
I noticed that it was previously owned by someone else, and the reset ring was broken.

When I placed this order, I knew that the ring has been fixed, and the Curta is in better condition(the outside look). When I bought, the Curta ended up higher price than previous trade, and that is understandable from my prospective.

However, I have one question. How can I tell if the replaced ring is metal or plastic? I assume the seller should have replaced it with metal.

Thank you.

Before you figure out whether yours in metal or plastic, check your serial number to see what it should be first: earlier Type 1s were metal, and later Type 1s were plastic.

You can do that here: http://www.curtamania.com/curta/code/type_and_age_of_your_curta.php
