Kessels "Muziekinstrumentenfabriek Den Haag" (1930's)

Originally manufactured between 1931 and 1934 by the local Kessels Muziekinstrumentenfabriek in The Hague, this B♭ cornet stands today as a fascinating hybrid testament to historical repairs and modern, hands-on restoration.

When this instrument first arrived at my home, it suffered from a major structural crisis. The bracing between the leadpipe and the bell section was entirely broken and missing. Compounding the issue, the main tubes were soldered directly to the valve block without any reinforcing structural supports.
A deep inspection reveals that the current bell is likely not original to the Kessels frame. It features a built-in pinky ring and distinct leftover solder scars on its left-hand side—hallmarks proving it was pulled from an old "French Wrap" model cornet. Whoever performed this vintage swap attached the bell at such an awkward angle that it physically blocked the third valve slide from moving.

Because the original leadpipe arrived completely cracked and leaking air, a bold replacement was required. A vintage leadpipe sourced from an old Couesnon cornet was meticulously fitted onto the Kessels chassis.
To correct the original structural weakness, brass braces were added to securely lock the new leadpipe to the valve block, and the bell section to the valve block. While these experimental repairs remain visibly raw, they fully stabilized the frame and provided an invaluable, practical training ground for mastering historical brass repair skills.

Because the replacement Couesnon leadpipe was originally engineered for a vintage European "High Pitch" standard, the modified cornet naturally plays sharp by modern standards. However, when paired with an elongated tuning bit, the instrument drops beautifully into alignment and comes remarkably close to Modern Concert Pitch B♭.
