* Change 2 Part Dark Bluish Gray {3794 Plate, Modified 1 x 2 with 1 Stud (Jumper) (Undetermined Type) to 3794a Plate, Modified 1 x 2 with 1 Stud without Groove (Jumper)} (Alternate)
Comments from Submitter:
Based on change log timeline, part was added as an alternate before 3794a was in the catalog, meaning it was the without groove variation until the catalog changed it to undetermined type.
