Train horn size

I got this from the site for the K5LA’s

Length: 16.25 in
Width: 29.75 in
Height 9.25 in

But I was wondering what the size was of each horn and manifold? Also can you put the K5’s in a different configuration or not?

Here is a CAD file I made of the bells. I haven’t measured/drawn the manifold.

I hope this shows up…I cannot see any linked image files right now.

You can mount the bells forward/reverse and swap positions on the manifold.
