Think I probably have more models of Aston Martins than any other marque.
These two are both Matchbox 1-75 series. The DB2/4 is No. 53a (first issue) produced from 1958 to 1963.
The F1 car is a DBR5, No. 19c, produced from 1961 to 1965. The original appeared in only one event when two cars were entered in the 1960 British Grand Prix: Roy Salvadori retired and Maurice Trintignant finished 11th. The failure of the R5 meant that Aston withdrew from Formula One and have made no entries since.
