| Eric- Those would be Soprano bugles in G. They date from mid '70s for the one valve and late 70's/early 80's for the 2 valve. They were used by drum and bugle corps. When I first bgan marching in drum corps in 1977, we used a G/D valve/slide bugle; the next coprs I went to had rotary valve bugles, then when I went to my 3rd corps we had the 2 valve. F.E. Olds and Donald E. Getzen were the 2 big names in 2 valve instruments, ranging from soprano, mellophone, flugelhorn, baritone and contrabass.
The one valve, as you may have figured out, acts as the 1st valve, and the slide pulls back to act as the 2nd valve. No 3rd valve combinations, so for a long time my aural concept of a C scale was quite bizarre.
There yoiu have it.
