National Washboard Co. No. 510 Value Guide

The National Washboard Co. No. 510 is a quintessential piece of mid-century Americana, prized for its durable wooden frame and ribbed glass scrubbing surface. Produced by a company with historic roots in Chicago, Saginaw, and Memphis, these boards are highly collectible due to their transition from rust-prone metal to fabric-safe glass.

What affects the value of National Washboard Co. No. 510?

• The clarity and condition of the glass surface, as chips or cracks significantly reduce the $35-$40 market value.
• Legibility of the original black ink stamps on the wooden header and side rails.
• The presence of original patina on the wood versus evidence of modern refinishing or sanding.
• Structural integrity of the frame, specifically ensuring the glass is still firmly seated within the wooden grooves.

How to Identify National Washboard Co. No. 510?

• Look for the 'National Washboard Co.' branding and the specific model number '510' stamped clearly on the wooden header.
• Verify the scrubbing surface is made of heavy, ribbed glass rather than zinc or brass.
• Check for the manufacturing locations of Chicago, Saginaw, or Memphis printed on the wood frame.
• Examine the joinery of the wooden frame, which should show age-appropriate wear and period-correct construction.

History of National Washboard Co. No. 510

Manufactured by the National Washboard Company, which operated out of Chicago, Saginaw, and Memphis. During the early 20th century, glass became a popular alternative to metal for the scrubbing surface because it did not rust and was less likely to snag delicate fabrics.
