I believe this violin was made by Johann Strad circa 1745 from what I can make from the label. However, I have not been able to find anything regarding Johann Strad. It was repaired by Joseph Winner in 1856. I found that Joseph Winner Sr. was a violin maker and also made repairs in Philadelphia, PA during the early to mid 1800's. The violin has a unique dove tail on the back. Any information of the age/maker would be very helpful and greatly appreciated.
