[406.] Duplicator, late 19th century and early 20th century. USNM 290936; 1970. This duplicator, a tube about 2½ inches in diameter and about 12 inches long, was used to copy farm records. The user wrote on paper with an indelible pencil. The original paper and copy papers were placed between two water-soaked linen leaves and all was rolled up on a wooden spool. Then the spool was inserted in the tube and left for a few minutes until the penciled ink stained through the wet papers and thus made copies. This specimen was used on a farm in Virginia. Gift of Mrs. Arthur Z. Gardiner, McLean, Virginia.
