Offered here is an exceptionally scarce Agilis 535 electronic calculator, complete with its original genuine leather protective case. This model is almost never seen on the open market and does not appear in current listings on major auction platforms, which makes it a highly desirable piece for collectors of early electronic devices. The Agilis 535 is documented in several online calculator museums and archival websites, where it is recognized for its elegant design, its blue-green VFD display, and its historical significance among European calculators of the mid-1970s. Despite being mentioned in these specialized resources, the model remains elusive in private collections, adding to its rarity and appeal. This example powers on and the display lights up, as shown in the photos. The keys currently do not respond, suggesting that the unit may need internal cleaning or repair. The calculator itself is in very good visual condition, with clean lines and no major damage. The original leather case is also well preserved and fits the unit perfectly. The item is sold as is, in the condition described. Because of its scarcity, its presence in online museum archives, and its overall preserved condition, this Agilis 535 represents an excellent opportunity for collectors searching for uncommon electronic artifacts. Will be carefully packaged for shipping.
