I have a 135mm f6.3 Wide Field Ektar that I am trying to find when it was made. According to the C-1 A-2 M-3 E-4 R-5 O-6 S-7 I-8 T-9 Y-0 chart my lens is either a '44 or a '48 or a weird combination of the two. It is EEI 1207, I have never seen another Ektar with three letters, ever. Judging by the spacing of the letters I believe it to be a '48, but what's with the extra letter? A mistake, an anomaly...the Holy Grail of lenses?
Any help?
Thanks
