Many of the secondary details shown at the right are also similar to the Leipzig horn, especially in the valve set. The round finger pallets and spring casings (top photo) are the same as seen on the Lepzig horn, although the valve linkages and screw tops are different. The valve caps (second and third photos) are distinctively Altrichter. The braces (fourth photo) are also identical to the Leipzig horn however the knob on the leadpipe is different, as are the pinky hook and heart-shaped bell brace plate (below).  The Leipzig horn also has a garland on the bell but this horn does not.

Altrichter horn, Leipzig, 3597
