I just picked up a Giant Sedona that looks late-80s to early-90s. I am curious about what year it was made. Here is some information:

- Serial # from BB is GZ833327 - all characters are readable except the Z, which could be a 7.
- Has a label stating it is Giant Sedona.
- Has another label stating it is Quad-Butted Cromoly.
- Has another label stating is was made in Taiwan.
- Is an 18-speed.
- Color is very dark purple that almost appears black.

I can provide information on the components as well, but I am not sure if they are the original.

Thanks in advance!
