SAAM has a large collection of Aircraft Parts that are stored for preservation and for future restoration projects and displays. SAAM also donates or trades parts with other museums to assist them with their restoration projects. It is worth noting that some WW2 era instruments have their dials painted with a 'glow in the dark' paint (radium). Recent advice is that they are safe as long as the glass front is unbroken. Nevertheless, SAAM has conducted tests with a Geiger Counter and would like to reassure visitors that instruments on display are safe.
