Sorry. Tried to include a link but it is blocked out.
Don't know all the details as my speciality is the 100e Prefects, Anglias, Escort, Squire and Thames cars. But as far as I know, they started building Escort Peranas in 1968 up to 1972. However, Escort Peranas is scarce even over here, and the favourite is the Capri Perana.
