This lens is for a Mamiya C220/C330 TLR (Twin Lens Reflex) Camera. Look around this site as I have two other C220 lens (6.3/250 & 4.5/55) listed. This lens is in good condition, internally clean of fungus, aperture works smoothly, has both the front and rear caps, and comes in a leather case (1910/bag).
Around the rim is written “MAMIYA-SEKOR 1:4.5 f=135mm No. 623532”
