I have owned this Type I Curta for more than 20 years, and it has spent all of that time carefully packed away on the top shelf in my office closet. It is in excellent condition and bears serial #21214. I will send detailed pictures to anyone who is interested. Please email me at rew4608@earthlink.net for more information. Thank you, Ron
THIS CURTA HAS BEEN SOLD. THANK YOU, RON!
