A money changer that was used by the public transport in almost the whole of Europe. These were used until approximately late 1975. After this, the electrical and digital payments were implemented. This conscious changer was used up to 1975 by conductors of the RET. (Rotterdamse Electrische Tram, the Netherlands). One copy is currently in the Rotterdam museum, dept. Transport. This changer is from the guilders age and still works perfectly. It is used with a carrying strap and belly straps and a pouch for a stamp and door key (these are not included). These changers were produced by SYRO in Switzerland and are virtually nowhere left to be found.
