Canon Extender FD 2x-A Tele converter

Cosmetically in excellent condition and it has both caps. I cannot test it and therefore it is sold as is for only $20. ________________________________________________________________________ PLEASE READ: ** AZ City is located 3 miles off I-10 Exit 200, halfway between Phoenix and Tucson. ** Pickup at my place, I will NOT meet you somewhere else. ** I accept cash only and I communicate by email.
