Special Riihimäen

Any collector of Riihimäen will recognise this as a Kehrä vase by Tamara Aladin from 1968-1976.
The enigma with this example is the colour. The standard colours as listed in the catalogue are clear, olive green & flint although the matching candle holders were produced in more, blue, amber & uranium.
Even my contacts in Finland have never seen one in Red before.
