Do you have a TT Blue Sub??
This is a study to determine the shades or hues of the various releases of the TT Blue..
If the results show promise this will become a TRF database for indexing and cataloguing the various production runs and hues.
Post a clear and focused picture of your TT Blue dial so color can be determined, along with the first 4 letter/numbers of the serial to determine approximate year..
If known, also add the region or location of the purchase.
If used, the contributors will be given photo and contribution credits..
