Sorry to hear about the eyesight
I thought the last two numbers represented the year the scope was made? Mine was 02 which sounds about right as the scope was 4 years old when I got it in 2006. Maybe I'm wrong. Also, the newer Tals are f/8.5. Not sure what year the focal length changed.
As much as I might want to consider one, money is needed to save up for the family to move. Plus, my work commitments don't allow me any time at the moment to use my scopes. Hopefully someone picks it up at astrofest.
