The handle features beautifully hand-engraved initials reading \"I.S.B.\", giving this compact optical piece a wonderful historical touch and personalized provenance.
Condition Details:
• Lenses: Excellent structural condition. Both glass optics are fully intact with NO cracks, fractures, or deep scratches. They provide clear, strong magnification when used independently or stacked together.
• Horn Frame & Handle: The swivel mechanism rotates smoothly on its central rivet post. Please note that there is an old, smooth indentation/recess along the outer edge of one lens frame where the horn has naturally worn down or chipped historically (clearly visible in the side-profile photos). The horn shows beautiful aged coloration and natural fibrous layers, but has this notable historic edge wear.
Sold strictly AS-IS as a wonderful historical display piece for optometry enthusiasts, coin/stamp dealers, or oddity curators. Please review all photos carefully to confirm the condition.
