Vintage Singer Model 15. AH378601 - January,1948

Singer Model 15 sewing machine (likely a 15-88 or closely related electric variant), manufactured at the Elizabethport factory in New Jersey, USA, in early 1948.

Serial number: AH378601

This falls in the AH-series block AH 378571–413570, which was allotted on January 5, 1948, exclusively for Model 15 machines at Elizabethport.

Full-size black Japan-finished head with simple gold floral/scroll border decals on the bed.

• Gold “THE SINGER MANFG. CO.” badge on the pillar.

• Lever-style stitch-length regulator (numbered 6–30 stitches per inch).

• Side-mounted Singer electric motor (Catalog B.R. 8S / Simanco, 110–120 V, 0.5 Amp, AC/DC compatible) — a common factory or period motor for these machines.

• Overall silhouette, faceplate, and bed shape typical of the long-running Class 15 (oscillating hook, drop-in bobbin style).

The Model 15 was one of Singer’s most popular and longest-produced domestic machines (produced in many variants from the late 1800s into the 1950s). Post-war examples like this one are solid, reliable straight-stitch machines.
