Antique Octagonal Tourte Branded Violin Bow ID & 1 other

[stubbsywubsy]

Hello Everyone firstly i am new to this forum so i apologise if this is in the wrong place
 
i recently came across these two antique Violin Bows,
 
one is a Tourte branded one which i showed to some freinds and they thought it was of a very good quality.
 
it measures 67.5cms long and it weighs 50grams including hair and grip which i understand is very light for a bow, it is also octagonal all the way down the shaft
 
if anyone could help me ID this that would be great
 
the other one is a round shaft non branded bow which measures approx 72cms long
 
and weighs 56 grams

both are german, the second is more interestant so is transitional. The first have  a german frog with parisian eye.

I think that these are ordinary trade bows.

 

These open frogs were put on cheap bows right into the twentieth century.

second bow is Ironwood or Pernambuco?, I can't see clear.
