Wippen/Whippen for US built Baldwin Artist grand pianos.  These are for the models with the Renner action - please note the design of the flange (2nd pic).  These also have a screw adjustment for fine regulation of the repetition lever spring (see 3rd pic) - if you've ever had to bend repetition springs to adjust them you'll appreciate this feature.  Previously installed on unused model SF action frames, I acquired these when the factory in Trumann, Arkansas liquidated in Oct 2018.  Made by Renner for Baldwin.

Please compare carefully with your existing wippens!  Older Baldwin grands had the more traditional flange - check your action to see if it is similar and accepts this type flange!
