We report on our attempt to identify the progenitor of the Type Ib PSN J12545218-1014502 (ATEL #3967, #3968) in archival Hubble Space Telescope WFPC2 images taken with the F450W, F606W, and F814W filters (GO-9042; PI S. Smartt). We obtained short-exposure (1 s), g-band and R-band exposures of the SN on 2012 March 15.51 UT, using the Low Resolution Imaging Spectrometer on the Keck-I 10 m telescope. We astrometrically registered these images to the WFPC2 image mosaics, using 6 fiducial stars in common between the two image sets.
