Canadian National Train Horn model 9000

I made this for my dad. He build large scale model trains with his train club. (the large ride behind trains)

Club Name - Indiana Live Steamers

If there is one person on this planet that might need this part besides my dad.. Here it is.

I made this with 123d Design.

Pretty much one of my first attempts at modeling something. More than boxes and rectangles.

The other piece slides over the top and holds the light. I will add a picture of that when my dad finishes mounting it.
