The valve caps are brass in color, not sure if it came that way or if it’s an upgrade. The tiny marks on the case are from being jostled around in storage. Two-piece valve construction: The valve casings are made in two pieces, with the upper balusters crafted from nickel-silver and the lower casings made from brass. Nickel-silver balusters: These contribute to the richer tone of the instrument, similar to vintage Mt. Brass casings: The lower part of the valve casings is made of brass. Valve guides: The trumpet comes with two sets of valve guides (brass and plastic) that allow for customization of the instrument’s response. Monel pistons: The trumpet features Monel pistons, which are known for their durability and smooth action, according to Conn Selmer. Other features: The AB190S also includes an extended 3rd slide rod stop, a 1st slide split ring, enhanced radius ferrules, and sculpted bracing.
