Would anyone happen to have the following dimensions for these horns? I tried looking it up, but can't really find anything substantial.

I am wanting to make some wooden ones for myself for a my pair of duplex's.

Here's the dims I need:

1) Inside of the mouth for one of the cells.

2) Inside of the throat for one of the cells.

3) Total length of one of the cells,down the center axis.

Thanks!
