Neck Truss Rod.
1928-ish: Ebony neck reinforcement under fingerboard for strength.
Late 1934: Steel "T" bar. Thickness varies, but generally speaking both sections of the T is 0.125", width and height is 0.525" (kind of like Flexible Flyer sled runners). The bar is glued into the neck with Hide glue.
1942: Ebony neck reinforcement under fingerboard (war time shortage of steel)
1945/1946: Steel T bar again used sparatically (varies between ebony and steel during these years.)
1947: Steel T bar.
1967: Square steel bar.
1985: Adjustable (inside body) steel truss rod.
