Old Violin Bow Stamped: "P.Serdet a Paris"

 Old Violin/Viola Bow Stamped:
*
“P.Serdet a Paris”
*
In my opinion, pernambuco wood round stick silver-nickel mounted, with new hair, head with a bone tip, ebony frog inlaid with pearl eye & adjuster with two rings.  
The bow was seemingly repaired at its tail tip (there is a silver ring there).
*
Length: around 29.5 inches, 75.0cm.
Stick: around 28.9 inches, 73.4cm.
The weight on my scales: around 63.5gr.

I am not a violin & bow expert and I am just selling these items as described. All bows and violins come from a private collection – the original owner has been collecting the instruments for around 40 years.
All items are sold as they are pictured in the photographs. Please, consult the photographs to get an understanding of the items condition, technical aspects and quality as a musical instrument, because I do not know and cannot judge, because I am not a violin or bow maker.
