I counted ~25 different stations mentioned K3s in the CQWW (several had multiple units). One was DL6FBL at SV9CVY using a TS-850 and lamenting that his K3 was not back from the VK9DWX expedition yet. :-) If he had the K3 maybe he would have heard me on 160! (I must have spent 30 minutes calling with no success). :-(
If you want to read the comments, look at the soapbox summary below and use Edit>Find "K3" in your browser. You'll have to skip over the other K3 hits (like K3LR) but just keep clicking Next until you see a genuine K3 mention.
