The TPBR-80 stop tailpiece (without screws). As used from the 1950s initially on the Gibson Les Paul, but later the ES-345-TD, and as the decades passed, many, many more. more.
The TPBR-85 (Tail Piece BRidge) bridge can either be used just as a bridge, or as a stop tailpiece, as seen in the first two images. As a tailpiece, the strings enter the neck-side, then wrap over the bridge. This simple bridge has no individually moveable saddles, but there are grub screws allow the whole bridge, or just one side to be adjusted slightly. Early versions were nickel plated, later they were chrome. Note the markings on the bridge underside - the Gibson part number TPBR8513 and 12809. As used throughout the 1960s on Gibson SG Special, SG Junior, SG-TV, Melody maker and Kalamazoo KG guitars more.
The Schaller wide-travel bridge first appeared on Gibson guitars towards the end of 1971, starting with the Les Paul Recording model, and soon followed by the SG Custom, Standard and Special from 1973. From then on, it became the standard bridge on all newly launched solid body and thinline models up until 1975: the Les Paul Signature, ES-325TD, L5S, L6S, Marauder and S-1. Towards the end of the seventies, many of these guitars were given other bridges, but the Marauder, S-1 and L6S kept the wide-travel tune-o-matic right through the course of their productions, into the early 1980s. more.
Gibson part number 80087 (chrome) and 80088 (gold). As used in the early 1980s on the Gibson Victory MV2 and MV10. This very cleverly designed bridge had a number of very useful and highly innovative features: easily adjustable intonation, easy bridge repositioning, easily changed saddles, and a slanted top to allow tailpiece height to be set right down against the wood. It is very surprising that this design was not more widely adopted.
