1973 Steinway Model L Grand Piano
Mahogany - 5'10" - Serial No. 435741

This 1973 Steinway & Sons Model L is a beautifully maintained mahogany grand piano that represents the finest of Steinway's American craftsmanship. The Model L-measuring 5'10½"-is prized for its powerful projection, rich tonal depth, and exceptionally responsive touch. Slightly larger than the more common Model M, the L offers greater bass presence and resonance, making it a favorite among professional players, teachers, and serious students.

Finished in warm, classic mahogany, this piano stands out both visually and musically. The serial number (435741) confirms its production in 1973 at the New York factory, a period widely admired for the consistency and quality of Steinway's build standards. It features Steinway's diaphragmatic solid spruce soundboard, the iconic continuous hard-rock maple rim, and the renowned Accelerated Action-designed to deliver precision, control, and expressive nuance.

Our technicians have fully inspected, tuned, and regulated the instrument to ensure optimal performance. It plays with a full, singing tone, responsive action, and impressive sustain across all registers. The mahogany cabinet maintains elegant vintage character, adding warmth and sophistication to any setting.

A wonderful opportunity to own an American-made Steinway Model L-highly regarded for its tonal richness, musical versatility, and premium craftsmanship. Ideal for homes, studios, and intimate performance spaces.
