I seem to remember buying the BT-3, but... I was pointed out in the comments that they are BT-2. The barcode on the instruction manual has the notation 20200N.

Bass Extender ■Color: Nickel ■67-82 Fender P & J Bass ■As many people have the image of Hipshot = Xtender Key, it is a Machine Head for drop tuning (lowering the tuning instantly) that is so well-known that it hardly needs to be explained. By using this Bass Xtender, for example, you can lower the tuning of the E string to D or C with a single lever, and you can instantly return it to its original tuning as needed.
