This tailpiece was used in conjunction with tune-o-matic bridges on mostly solid body, but also some Electric Spanish guitars, from Les Pauls, and the ES-345TD in the 1950s, through Firebirds, SGs and, at some point or in some variation, just about every other major solid body guitar in the Gibson line ever since. As it was only ever a tailpiece, and never needed to move for intonation purposes it did not have the grub screws behind each post.
The part number for this bridge changed over the years, summarised in the table left - it was included in 1950s Gibson part lists, but was not numbered. Naturally there has been some variation in this component over six decades, most obviously in plating: either nickel, gold or chrome.
