Just found these N1201-8A crossovers (Model 19 design) on Ebay currently at $26.55 with no reserve. Obviously they'll sell for more but if they're mint as advertised they're worth a lot more.

A different seller has two pair of factory Model 19 Cabinets (NOT home made replicas) currently at $9.99 with no reserve--look to be in overall good shape. You just don't see these factory cabs and Model 19 (N1201-8A) crossovers in good shape every day so I thought I'd give a heads up.

Add a pair of 811B horns (pretty common) like these (with original boxes and mounting hardware--currently at $21.50 no reserve)

Buy some brand new 802-8G's and 416-8B's from GPA, stir and season to taste, and you're ready to ROCK!
