Hola. ¿Cómo se traduce "dull weight" en el texto siguiente?: A great oak shell: the lid was outside in the porch, Mr. Tressels was unwilling to screw it down, having heard that the entrance to the vault was so narrow, and apprehending it might be necessary to take the coffin out. So it lay its length with a dull weight on the two forms. The lead coffin inside, with its dusty black velvet, was plainly much older.
Gracias por vuestra ayuda.
