Project Legacy · Historical Product Evidence

A remembered product name can become a source-bounded research path.

Legacy now indexes 38 named historical product entries transcribed from two official asbestos-trust product sources. The purpose is identification and orientation—not to turn a product-name match into proof of exposure.

Why this matters. People often remember a label, bag, brick, cement, insulation block or trade name long after they forget the supplier or exact employer. That memory can be searched without treating it as proof.
