Here are a few horns from Richard Burdick's collection

His primary instruments are:

A Durk D3 with a sterling silver leadpipe
and a Lawson Ambronze bell.
(now back to the original lead pipe and a silver bell made by Monke)

A 1840's Austro-Bohemian Hand horn
rebuilt by Lowell Greer with some L. G. crooks
He believes it is a horn made by
Marcel-Auguste Raoux

And now this one:(see below)

 

---

This is my new horn, a Couesnon horn made about 1913 -
It has the most gorgeous tone of all my horns!

This one is an original FRANCOIS PERINET Cor de chase it's in D.Or maybe in low pitch Eb

The bell reads: " FRANCOIS PERINET RUE COPERNIC 27 PRES L'ARC DE L'ETOILE A PARIS"

It has the original mouthpiece mark "3" I think it was made around 1870 (1870-4).

 

In the picture at the top Mr. Burdick is holding his Durk D3 with a nickle plated belll made by Joseph Monke
For the Durk, he has a collection of bells:
The stock bell (1) is gold brass (more zinc than copper)
I have an Atkinson (2) that is really nice
A bell from my Monke single F (3) that is nickle plated and very heavy (that's what is in the picture.)
and an ambronze by Lawson (4)

With recording tests the Small Atkinson wins on everything exceptit doen't have the best tone.
