The majority of CL-44s were CL-44D4s which built (not modified) with the swing tail. The only ones built without it were the 12 CC-106 Yukons for the RCAF. The all passenger CL-44Js for Loftleidir were converted CL-44D4s but I'm not sure on those if the mechanism was disabled, or whether the swing tail was removed entirely when they were stretched (which is I think more likely).
