Who can tell me something about a Mecanica Nacional Fuerza Libre car called
La Unión Especial No. 1?
Apparently this was at first an engine, build by Leopoldo, Luis and Mario Niemiz plus Marcelino Dumé in Paraná, Entre Rios, Argentina to race in the unlimited Argentine national racing class. Who knows about the chassis used when it seems to have debuted at around 1956? As late as 1960 the whole car was still considered as an outstanding enterprise (Praga, Historia de una passion, p. 731).
Any more info available, some race results on hand? Many thanks in advance!!!
