Thanks, Noel - yes, they are all 1/24 scale - the Simca has been released about 15 years ago in the Italian Quattroruote newsstand series with opening hood, doors and trunk. It has been reissued several times in different series (all made by Ixo) but without opning panels.
For instance,Modelissimo (Germany) has it for € 17,96 (stock version) and for € 19,95 (rally 2) - click on the following link : https://www.modelissimo.eu/ and then choose scale 1/24 and "Fabbri Editori" for the stock and "White Box" for the rally 2 .
