Olivetti LOGOS 58, elektromechanical printing calculator, adored example of avant garde office-equipment-design, cleaned, in function condition.
good to excellent preserved for age, very few tiny burst-spots on laquer, bottom left marginal white-patched and top right residue of removed labels , back side yellow label. all cleaned with NH3-cleaner, even the keys (see pictures)
all vacuum cleaned inside , key- and start-panel disassembled and oiled (MoS2-spray) resp. greased (start-lever). print-device oiled (not demounted). Inspection did not reveal wear, brocken parts, burns/swelter etc.
function (result of test) Caution: push REGS CL-key first
all keys jump back into rest position quick and reliable. on-light glows. some calcultions have been performed: the results have been printed exactly, justage of the digital-point-trailing columns reakts with correct number of digits on paper. Print is sharp and with regular distance of digits but weak because of the old ink-tape cartridge. One will restore this provisional by stamp-ink- treatment.
