Now here is something you don’t see every day! This is a Kruspe trombone – probably model Penzel – from before 1918 in excellent condition! It is made of yellow brass and has a large bore – similar to a modern Bach 42. The bell features a wide Kranz and is approximately 9.5 inches wide. The engraving says “Ed. Kruspe, Hoflieferant”. The inner slide seems to be original, but chrome plated afterwards.
For an instrument of this age, it is in exceptional condition. No dings, no dents, not even scratches. I suspect it hasn’t been played in a long time as the slide is quite scratchy as of now. But it gets better day by day.
