Derringer revolver, exact unknown model. It is possibly a cap gun made by the Spanish company, Redondo. Redondo was a Spanish toymaker founded by the end of 1949. It was based in Aldaya a small town in the province of Valencia By the middle of the last century, the town developed rich industrial activities with furniture, brick, hand fan and toy factories. The population back then was around 6400 inhabitants, but grew quickly and today it has around 30.000 inhabitants. The toy factory was, of course, Redondo. Redondo was never one of the “top” toymakers in Spain, but somehow “second class”.
