INTRODUCTION
The aperture control switch is labelled with MAN/AUTO and the model number is inscribed on the back face of the switch. The production period straddles the opening of the Mashiko plant in Tochigi Prefecture and the start of 6x7 lens manufacturing in 1969. No changes were made to the lens during this period. The words "Super-Multi-Coated" are not used on 1:2/55 lenses; much later "SMC" is used instead.

NOTES
LENS PRODUCTION (∑ lenses) ∑n = 1001 Serial Numbers observed in 129 Batches covering 80,512 SN min. < ∑ lenses < 112,960 SN max.
SN min. = accumulated total of serial numbers observed within 129 batches
SN max. = accumulated total of serial numbers observed between adjacent batches of other lenses.
One style: Letter font is "cursive", oval with open "4". The serial number follows the lens name; and no comma follows the maker's name.
Aperture ring coarse knurled. Focus ring formula and Aperture ring formula F=10/12 and A=10/10 throughout.
