You would need to check the engine number to be sure. If it is original the finned rocker covers came in 1967 also from that year the engine and frame numbers were the same. A65TA would be a Thunderbolt A65LA would be a Lightning A65FB would be a Firebird A65SA would be a Spitfire. The petrol Tank looks like the 2 Gallon export tank and with the single carb on looks I would say it is a Thunderbolt but engine number and frame number will prove what it is.
