How much trouble and expense are you willing to endure? There's a one-owner "mint TT Eagle w full complement of filters on eBay right now. 15 bids and $616 (!) so far. You could, I suppose, bid on it, and if you get it, pull the filter and try to resell the extra rig for a lower price after pulling the filter. Methinks you'd lose money that way, but maybe not so much as to make the idea totally absurd. It's a lot of bother for a filter. It might be more reasonable to look for a "parts only" Eagle if you can verify that it has the wanted filter. A saved search on eBay for the exact filter w part number might eventually turn up just the filter. I'd definitely try that route. And, certainly post a WANTED classified on eHam.net. Good luck from another TT owner!
