Hi Zach. I've never seen them - but I know Giles Brown of Dorset Soldiers does a "Band of Angels" with a Conductor and around ten Angels playing some unusual musical instruments. (e.g Mandolin, Pan-pipes, Tambourine etc).
Maybe send Giles an e-mail and ask him to send you a pic?? You can then see if these fill a vacancy.
You could either ask for them painted - or even as castings - if you have someone local who could paint them for you???
Best of luck - jb
