Viola bows
Copy of an early, c.a. 1685 baroque bow, probably Italian, with a separate frog. Without the frog the stick has no curve. Only after tensioning it, it gets an outward curvature: approx 50-52 grams
High Baroque bow from somewhere around 1740. Everything (stick, frog and button) made from snakewood. It weighs circa 55-59 grams.
Classical bow, c.1770, based on an original for violin. The stick is ironwood, the frog and button are mastodon: 56-60 grams.
Early Romantic bow, probably Vienna 1800-20 with a snakewood stick. It is longer and a little heavier than the previous bows. The frog and button are mastodon, the stick is snakewood.
Weight: ca. 63 grams. A great bow for playing Mendelssohn and Beethoven!
Modern bow after Peccatte with ironwood stick. Weight: 72-74 grams.
