Peace Small Lef .
Made late 1940s begin 1950
Very small twin lens reflex camera.
Uses 17,5mm rolfilm.
And takes 12x14mm rectangular pictures.
On the lensing is a serial number No 1032.
And the letters S P S.
On the back is a small red window surrounded by a diamond shaped metal frame.
The lenses have no name, the shutter is an Everest with B & I.
This camera sis almost identical Peace Baby Flex.
The “Lef” is probably a misspelling of “Ref, an abbreviation for Reflex.
Pronouncing of these words Lef & Ref is the same in Japanese.
Probably the smalles twin lens made.
A hard to find camera.
