I would agree with masispecial. Compared to my serial number it makes sense. The fork crown was not sloping in 1982. I do recognize the "C" lug cutout which is also on mine. I say this is pre-1982, either 80 or 81. Mine also has braze-ons for the downtube shifters and second bottle cage but similar to yours. Cannot be certain but all the models I ordered in 1982 came with downtube braze-ons for shifters as stock and had to specify to make without them.
