WANTED: 2 2.8KHz filters

Lou Laderman W0FK

I'm looking for 2 2.8KHz filters to replace the 2.7KHz's in my K3S. In addition to just buying them outright, I can offer a partial trade by throwing in my 2 2.7KHz's plus cash, or swapping some combination of 2 400Hz or 2 250Hz filters. 
Please email me directly at lladerman AT earthlink DOT net.
