The Reed & Barton 1158 1/2 mark appears on silver pieces produced by Reed & Barton, one of America’s most respected silversmiths. The number 1158 refers to the base pattern or design, while the fractional 1/2 indicates a size or style variation, often denoting a slightly smaller or modified version of the original model. This precise system of marking allowed Reed & Barton to maintain a detailed product catalog and ensure consistency in production. Pieces with this designation are appreciated for their craftsmanship and nuanced design.
