Non-standard Make & Model Top Caps
While we have Mod Kit components to fit hundreds of brands and models, sometimes we don't have your specific instrument available. Add this item if your trumpet is a non-standard size requiring samples to be reproduced. Jason will need to measure thread pitch, shoulder heights, diameters, etc. to make you a custom set of Harrelson top caps to match your trumpet. This is usually required with low production instruments, vintage, and antique instruments.
