Ultegra Brifter Family Tree

Can someone give me the chronolgy of the ST-6500 series of Shimano Ultegra brifters?

I assume that the ST-6500 is the base model, introduced about 1998 or so. I'd like to find out just
what the difference is between that model, and the ST-6501, ST-6510, et al.

I've searched thru the Shimano sites, and all the reference material that I have on hand, but can't
come up with definitive descriptions. Info requested as I'm finally going to get rid of those noisy
ST-6500's that came on my bike, and need to get an idea of how far up the "tree" I have to go.
Flightdeck stuff is of no interest, so if I can avoid that expense, it would be very helpful.

TIA

Doug - you can e-mail Shimano Europe and ask. The address is [email protected]

I asked for the same info for Shimano 105 shifters -

Question - what's the differences between ST-5500, ST-5500-C, ST-5500-CA, and ST-5510?

Answer - Between ST5500, and the rest, ST-5500 is non flightdeck compatible, as all the others are
flight deck compatible. From C, to CA, some internal improvements. From CA to 5510, facelift.
