Well it's certainly tempting to think that those two frames were made in the Fairly works (which I think is owned by Giant). It was only the '88' and 90 Konas that had T numbers (Taiwan). By 1991, the frames were made in Fairly and Hodaka - for example, F104 4149 is a 1991 Cinder Cone.
Unfortunately the rest of the number on these two appears to be in a different kind of format, and it may well be that it doesn't tell us anything about date. That is, not unless they were made in 1983, which seems too early.
I wonder whether Joe Murray can remember when he started designing bikes and bike parts for TBG - they seem to claim it was quite a while before the Kona brand came out.
