This is a full-depth, single-P-90 Gibson ES-125 with the following original or period-correct features that collectively date it to the early 1950s, most consistently around 1950:

• Pickup: Black dog-ear P-90 with six adjustable screw pole pieces. Gibson switched the ES-125 from fixed/slug poles to adjustable poles around 1950; this is the later style.
• Fingerboard: Round pearloid dot position markers (standard after the brief late-1940s trapezoid phase).
• Tailpiece: Original-style trapeze with raised diamond on the crossbar (common on early-1950s examples; documented on at least one 1951).
• Headstock logo: Gold silkscreened block “Gibson” logo of the early postwar type (phased in ~1947–48). The “i” dot is consistent with the early block style (generally 1948–1951), before the later free-floating-dot refinement.
• Control knobs: Tall gold numbered barrel/speed knobs (0–10 scale visible through the clear plastic). These match the 1949–1952 style; shorter speed knobs and bonnet/top-hat knobs appear later (mid-1950s onward).
• Tuners: Replaced (white plastic buttons); Replaced tortoise shell pickguard and bracket, all other major components appear original or correct for the period.
• Identification: No visible FON or serial number in the f-hole or on the headstock (not uncommon on these student models and does not contradict the feature dating).
