Based on the fittings, the frame would appear to be late 1970s or early 1980s. I've made a hobby of studying serial number codes and this one could be a Panasonic frame if the 2nd character is the number "zero", as opposed to the letters "O" or "Q". In that case, it would appear to be a 1980 model. Most manufacturers tend to skip the letters "I" and "O" in their serial numbers, as they are easy to confuse with the numbers "1" and "0" if the impression is not complete or the paint fill is excessive. In your case, you already have a known number zero (ie 2016), so take a close look and see if their is any difference in shape. If it's the letter "O", I would expect the shape to be different, likely more full or rounder. Good luck.
