Vintage HP-15C Scientific Calculator with Case Hewlett-Packard Voyager Series. Calculator works well. Calculator is missing the HP-15C emblem on the front right corner. Furthermore, in full disclosure the battery compartment has some corrosion. After cleaning the compartment as best I could and testing with new batteries the calculator works well. Requires (3) size 357+ button size batteries which are not included. Overall in decent condition with some minor surface marks. Made in the ...USA. Please see photos for details.
