Abstract
The Battleship North Carolina, one of the most decorated American warships from the Second World War, is a floating museum designated as the state's WWII memorial to the 10,000 men and women in all branches of services who gave their lives in battle. One of the unique items on loan to the museum’s collection is a rubber terrain model map shown in three-dimensional relief. While this style of map was not uncommon during World War II, these model maps are historically significant and present new challenges for conservators to preserve both the original intent of the object and the material it is made of. Working closely with the curatorial staff, several objectives for the treatment were identified including methods for transporting the map through the tight bulkheads of the ship, accommodating the museum’s unique storage needs, mitigating the deterioration factors of rubber, and ensuring the overall preventative measures would not impede the accessibility of the map. Addressing these treatment goals involved manufacturing a custom-made Plexiglas support to aid in transportation and transition from storage to display as well as to create an oxygen-free microclimate for the stabilization of the map’s rubber components.
Résumé – Le cuirassé North Carolina, l'un des navires de guerre américains les plus décorés de la Seconde Guerre mondiale, est un musée flottant consacré à la mémoire des 10,000 hommes et femmes de la Caroline du Nord, de toutes les branches des forces armées, qui ont donné leur vie au cours de la Seconde Guerre mondiale. En plus d'abriter une collection variée d'archives, d'artéfacts et de textiles, il représente aussi les autres navires précédents qui ont porté le même nom. L'un des objets uniques prêtés à la collection est une maquette de terrain, une carte topographique en trois dimensions, faite de caoutchouc. Bien que ce style de carte ne fût pas rare au cours de la Seconde Guerre mondiale, ces maquettes sont valorisées pour les connections historiques qu'elles portent, tout en présentant de nouveaux défis pour les restaurateurs qui doivent préserver à la fois l'intention originale de l'objet et la matière dont il est fait. Une étroite collaboration avec le personnel de la conservation a permis d'identifier plusieurs objectifs pour le traitement dont des méthodes pour le transport de la maquette à travers les étroites cloisons du navire et l'assurance que l'ensemble des mesures préventives n'aurait aucune incidence sur sa visibilité.
Resumen – El buque de guerra North Carolina, uno de los barcos Americanos mas decorados de la Segunda Guerra Mundial, es un museo flotante designado como el monumento de Carolina del Norte a los 10,000 hombres y mujeres del Estado en todas las ramas de servicio que dieron sus vidas durante la Segunda Guerra Mundial. Además de su diversa colección de archivos, artefactos y textiles, también representa a todos los barcos llamados North Carolina. Uno de los objetos únicos, en préstamo a la colección, es un mapa tridimensional de goma/caucho modelo de relieve de terreno. Siendo que este estilo de mapa no era fuera de lo común durante la Segunda Guerra Mundial, estos mapas son significativos y presentan nuevos desafíos de preservación para los conservadores en el empeño de preservar tanto la intención original del objeto como el material del que esta fabricado. Trabajando de cerca con el personal de curaduría, identificamos varios objetivos incluyendo métodos para transportar el mapa a través de los mamparos angostos del barco y asegurar que las medidas preventivas generales no impacten la visibilidad del mismo.
Resumo – O encouraçado North Carolina, um dos mais condecorados navios de guerra norte-americanos da II Guerra Mundial, é um museu flutuante apontado como monumento do estado da Carolina do Norte aos dez mil homens e mulheres, de todos os ramos de serviços, que deram suas vidas durante a guerra. Além de uma variada coleção de arquivos, artefatos e tecidos, também representa todos os [outros] navios denominados North Carolina. Um dos itens exclusivos em empréstimo à coleção é um mapa modelo com terreno emborrachado em relevo em três dimensões. Apesar de esse estilo de mapa ser comum durante a II Guerra Mundial, esses mapas modelos estão imbuídos de significado e apresentam novos desafios de preservação para conservadores, a fim de manter o propósito original do objeto, tanto quanto o material o qual foi confeccionado. Em trabalho conjunto com curadores, foram identificados vários objetivos para o tratamento, incluindo métodos de transporte do mapa por meio de anteparos justos [firmes], garantindo que medidas preventivas gerais não impeçam a visibilidade do mapa. Addressing these treatment goals involved manufacturing a custom-made Plexiglas support to aid in transportation and transition from storage to display as well as to create an oxygen-free microclimate for the stabilization of the map's rubber components.
