Recently discovered in an old draw - once belonged to my grandad. I purchased x6 AG13 batteries - only requires 3 but will include the other 3 as spares. Seems to work as it should, but i am not an expert. Please see descriptive photographs. In great condition includes original slip case. Key Features: Authentic Hewlett-Packard HP 12C model Designed for financial, business, and investment calculations Vintage edition – ideal for collectors and professionals Compact, durable, and user-friendly design.
