Out of Mothballs: Obsolescent Weaponry on the T2k Battlefield

[Vespers War]

On the East Coast there's the AAF Tank Museum in Danville, VA (on the North Carolina border). The collection there includes:

US armored vehicles:
M1917, M4A3E8 Sherman Bulldozer, M5A1 Stuart, M18 Hellcat, M47 Patton, M48A5 Patton, M103, M41A3 Walker Bulldog, M60, M60A2, M60A3

German PzKpfw IV Ausf H, Soviet T-34/85, Iraqi T-54 and T-72

A half-dozen APCs and their derivatives (M59, M75, M113, M114, M163, M901)

Some of the vehicles (I don't know which, but posts from people who have been there say "most of them") are in running condition and are driven on demonstration days. It wouldn't have been as large in the Twilight War, since the original museum was in Mattituck, NY, and much smaller; it moved to Virginia in 2003 (according to a news article, the move consisted of 2,597 tons of stuff). For someone running a later timeline, though, that could be a treasure trove of materiel.
