GIBSON PTTP-070 Lightning Bar Tailpiece

This is a GIBSON PTTP-070, commonly known as a Lightning Bar tailpiece.
It's a type of wrap-around tailpiece with added compensation for octave tuning. Unlike vintage parts, the protrusion for the 3rd string has been adjusted to accommodate modern strings.

I purchased this part individually and used it for a while, but I felt it didn't suit my guitar, so I removed it and kept it in storage.

While searching for the model number, information suggests it's made of aluminum, but it weighs approximately 72g, so it's likely made of zinc die-cast with nickel plating.

Since it was actually installed, there are marks on the protrusions, where the strings make contact, and where the studs connect, indicating some signs of use. I don't think these will be very noticeable when mounted on a guitar, but please judge from the photos.

The studs that came with it are also included. These also do not attract magnets, so they do not appear to be made of steel.

How about this for those who have guitars with wrap-around type bridges, such as Les Pauls, SGs, Juniors, or Specials, and want to try replacing their bridge?
