Years ago, my Dad bought a Rover P5B, which coincidently, topped out at around 55mph, went throught the gears very fast and was absolutely screaming its Knutts off. I took it to a P5 specialist who removed the diff to find it was from a Land Rover, he replaced it with the correct diff for the car and hey presto, gearing was back to how it should be, your car (at some point in its 50 odd year old life) may have had a diff from say a W110 220D, (if compatible) which could possibly create the effect that your car is giving you, seeing that it seems you have all 4 forward gears, If it were me, I would remove the diff and check the ratios,
Hope this helps and good luck!
