Who did what?
I don't know who designed the grips but I know the floral fancy grips originated on the various Bulldogs. Extremely common. Some collectors focus on the grips alone. Since there are so many designs found. All the exact same period as the S&W mod 2 DA TB 32.
Dragons, elephants, pirates, birds, dogs, many animals, even odd looking serpents.
I also know that the 32's were targeting the female client seen in many advertisements of that era.
