Olympia 50s/60s calculator

Mechanical calculating machine from the 50s/60s. No batteries or electrical connections, so you can do your accounts "for free" just put a roll of paper. Be careful it's very heavy, at least 5 kg. For collector or DIYer because there may be a little greasing/oiling to do. Complete with all its parts.
