Anyone have a 3+1(4v) Conn Worcester Eb Tuba?

Going to see the horn this week. It is silver, serial # dates it to c. 1887, Conn Worcester Eb 3 top, 1 side pistons.
Here it is:

Anybody have a similar horn? Doing some research on this.
If anyone has a similar one, can you send me a jpeg of yours? My email:

That's a double rare beast you have there! Worcester was a short run and 3+1 wasn't a common offering/purchase then.
