Saddles History

I'm looking to pick up my first Tele. I have a line on a '94 MIM, but I notice on the picture it has what looks like six vintage looking saddles (as opposed to three). When I Google "94 Telecaster" most of the images come up with the graph tech looking saddles. That got me curious; when did Teles go from three vintage style to six to graph tech to bent Strat-like saddles? Or maybe MIM's had different saddles than MIAs?

There are many different models of Telecaster with various types of bridges and saddles. '94 MIM Telecaster isn't much help. Which model are you referring to?

Relevant to my interests.

All the description said was "USED 94' FENDER TELECASTER OCEAN TURQ" but I called in to find out more and it turns out they sold it, so I guess it doesn't matter.

Here's the 2000 MIM saddles...
