Trumpet / Cornet ID rotary valve

[bbb21]

I've been striking out on google, so would anyone have any info on this, not sure if it is technically a cornet or trumpet. It has 4 rotary valves. It is marked on the bell, but the old time cursive, not sure what it say, FM Swan & co?, the "wan & co" is distinct , not confident on the first 3 letters and/ or if the 3rd goes with the wan. Under that it is marked Burlington. If anyone has any info on it, I would appreciate it. Thanks . Th

This appears to have a cylindrical bore, not a conical bore, so it would be a trumpet.
