There should be a paper label inside the violin that you can see through the S form openings - what does it say? Also, check the ends of the bow to see if there is a stamped mark and send a photo of the curled end of the violin.
Thank you for checking. Please check the bow for marks and send a side view photo of the 'curl' at the end of the violin.
Thank you for the images. There does appear to be a impression stamped maker mark on the bow on the end with the ebony piece and right before the leather bit around the bow stem. Can you read it or send a more clear, in-focus image of that area.
I will opt out here and open your question again to all the experts. If someone knows the answer, they will respond to you here.
I hope you find the information that you seek.
