With the Plus model Purma returned to using a metal body rather than the plastic of the Special. It was manufactured by Purma Cameras Ltd at their factory in Wales. The shutter is similar to that used in the Special. The finish of the camera was very poor and few are now in good condition. The price reduced over time starting at 12.12.0 in 1952, 11.10.0 in 1953 and 7.19.0 in 1954. The Plus sold in large numbers.

Three versions of the Plus were produced:

  • Original with plain metal body.
  • Second version (c. 1953) having a lens tube of constant diameter rather than a having a larger flange at its front. This model incorporated a safety lock to prevent the shutter from being released when the lens was retracted (i.e. when the lens cap was in place).
  • A red plate carrying the Purma name was added to the face of the camera, and a small red plate carried the I, B markings surrounding the shutter release.

Accessories:

  • Flash outfit.
  • Lens hood.
  • Lens ring to hold filters or close-up lenses if lens hood is not used.
  • Filters - Yellow, Orange, Green, Blue, Red.
  • Close-up lenses numbered 1 to 6, focus 18" - 120 ".
  • Cable release.
  • Ever-ready case.
  • Accessory wallet for 6 supplementary lenses .
  • Accessory holdall, attaches to Ever-ready case and holds wallet, lens hood, cable release and filters.
  • Camera carrying lugs and sling.
