Hi there! I have had this bow for about 10 years and haven't used it very much. I originally bought it from a student at Oberlin. It works quite well with gut strings and decently with steel. Bows like this were quite common in the mid 19th century and they started to have thinner sticks, more camber, and closed frogs towards the end of the 19th century. This example has an tall open frog with a screw that functions well. The tip of the bow is a bit "crude" but it draws a big sound and is well balanced. There is no stamp and I am unsure of the wood. The frog is probably a bit taller than a regular german bow frog - my hand is small.
