ebay, advanced search, click the sold listings, and using first model Ka-bar for a search gave me 3

one was sold at $195
the other 2 were priced at ~$275 but best offers were taken (no way to know what that offer was)


if that helps, tho I am not sure how they compare to yours in condition


other than Gunbroker and Ebay, I do not know of a site that shows sold prices,
