I hope you mean 2005 and not 1993!
Funny thing is I think I have one or two in progress from before '93!
I too have a Tamiya M113 in progress, albeit the A3. Add to that Trumpeter's M1126 Stryker, Tamiya's Stug IIIG, an Italeri M4A1 Sherman, and Trumpeter M1A1 Abrams (those last two definitely meet the "Pre-'05" criteria!)
Somewhere tucked away, I have an M577A2 and M48A5, both Tamiya (with the Lo Model A5 conversion for the Patton), painted but needing a re-do...someday!
