Don, I believe you have the correct TCR numbers for all three (they should all have a ".1" after them since the green tail versions are listed that way, but the numbers are correct). The first 2 listings currently in The Chip Guide for the dovetails are incorrect.

The top chip should be listed as N3685.1 (same as your 3rd chip). The next one down should be listed as N3685 (the red tail version of the top one).
