It is your point, but it is from 1934 and it is technically not a Méray as it was partly developed by Magyar Acélárugyár rt (Hungarian Factory for Steel Goods) and it was also manufactured by them. It was equipped with a radial engine and about 9 were made with truck bodies and one chassis featured a passenger car body.
In the first edition of my book on Méray there was just a grainy photo of this elusive prototype passenger car, but now I have four nice pictures of it. The 2nd edition will be out in October (fingers crossed)
