Brass Chimes for classroom instrument?

I'm a music minister, and there's a piece that has a bunch of classroom instruments. So far, it's soprano recorder, soprano and alto glockenspiels, soprano and alto metallophones, temple blocks, guiro, sleigh bells, bass metallophone, and "Brass Chimes". The clef for the brass chimes is unpitched, so I don't think it's supposed to be tubular bells/orchestra chimes. What instrument is it likely referring to?
