Looking at late 50's to early 60's
Most fighter aircraft of this time could be fitted with bombs or rockets and as they were overtaken by better models often were retasked with a ground attack mission.
There were also a lot of ex WW2 fighters and light bombers remaining in service in Sth America, Africa & Asia performing this role.
Looking through my big book of aircraft I can add the following to the list.
Hawker Hunter, Blackburn Buccaneer, Fiat G91, Gloster Meteor, Dassault Etendard IV, Ouragan, Mystere & SuperMystere, DeHavilland Vampire, Sea Vixen,Venom, Douglas A3 Skywarrior, A4 Skyhawk,A1 Skyraider, EE Canberra, Grumman F9F Cougar,Hawker SeaHawk, Martin B57, McDonnell F3H Demon, NA F100 Super Sabre, Supermarine Scimitar & Swift,
