The horn didn't have external threads in it. The cavity came almost to the very tip. The internal threads with the collar was just the ticket. I lked the curve and the color( rather translucent) so I just had to listen to the horn.
When we met at Rase's early this month, Scott Morrison and I went over it and he suggested dying the bands and not the horn. I agreed with that and I think it was a good choice. Thanks Scott.
The tip is an old one that I didn't like on it's original horn. I reshaped it and t worked well. Waste not!!!
Thanks for the comments guys
