The Ensign Selfix 420 was a folding camera sold by Ensign from 1946. It was fitted with an Ensar Anastigmat lens and took 120 film with the ability to expose either eight 6×9 or twelve 6×6 frames with the optional application of a mask. It is very similar to the Selfix 20 which it succeeded.
The Selfix 420 is not a rare camera but it is much less common than many better known folders.
