For an art project? I would not recommend vintage instruments for any such project- use more current equivalents- First, they are in limited supply, and are needed if in airworthy condition, for aircraft that may still use them. Second their price s usually more expensive. Third, and very importantly, many contain Radium on their markings, and this can be a health/radiation hazard to you. (There is an apparent movement underway to control possession of these same radium marked a/c instruments, I understand)
So- for an art project, I recommend finding newer, non-radium, non airworthy instruments...
Whatcha planning on anyway? Sounds like an interesting project concept.
