(Research Note: Since 2020 I have seen 2.00% (73 copies) of the total estimated 3,644 copies made.)
INTRODUCTION
Batches of this first accessory lens began to be produced for the ASAHIFLEX I in early 1953 when the first version of the standard lens entered mass production. The lens remained in production, unchanged optically, throughout the reign of all ASAHIFLEX camera models and into the early M42 screw mount period for the ASAHI PENTAX. The former were made of chromed brass and out number the latter which are clad in black.

DESCRIPTION
A 3/3 element lens made of brass with a silver chrome-plate finish. Aperture ring distance units are either "Meter" or "Feet"; not both. The symbol for infinity is shown on the former and an abbreviation (Inf) of the word on the latter.

VARIATION
Some early copies have coarse fingers grips on the focussing ring. Copies for export with "Feet" on distance scales out number those with "Meter" scales by 8 :1.
