These are high level master made pernambuco bows from Europe, made by a bow maker I have had experience of in the past through his work for a major European maker. I always liked his bows but have been unable to get them for the last four years. He now makes bows independently under his own name (which I am not to reveal openly but the bows are stamped with his name) and also for a major German maker.
The violin bow is available in round or octagonal stick. Viola and cello bows are octagonal. Weight: violin bow 60 - 61g, viola bow 70g, cello bow 80g.
