This is a Wright & Ditson Mercer Beasley Signature Model Wooden Tennis Racket. Comes with Spalding Head Cover and Head Press. Mercer Beasley model with Wright & Ditson Logo  instead of Spalding on its throat. Head cover and wood press has SPALDING signature. From this combination, I assume that this racket was made in the early stage after the Spalding took over the Wright & Ditson (1870 ~ before 1900 ). About Wright & Ditson (Info at woodtennis.com / From here ) George Wright and Henry A. Ditson each owned sporting good companies in the 1870s. Wright & Ditson company was founded in 1871 and was bought by Spalding in 1891, however the name was continued on tennis rackets & balls till into the 1940's. In the 1930s the company's name was "A.J. Reach, Wright & Ditson and ownded by Spalding since 1891. Al Spalding, A. J. Reach and George Wright all played for Boston's National League baseball team in 1877. These 3 athletes and business men were all key players in the early sporting goods and athletic apparel in the late 1800's and early 1900's. For more detailed information on these companies and specifically the lawn tennis history and equipment including rackets, balls & cans I recommend reading the excellent sections in Book of Tennis Rackets by Sigfield Keubler or Tennis Antiques and Collectibles by Jean Cherry. Regarding tennis rackets, up until 1882 lopsided or tilt top rackets were made. After 1882, triangular flat top were produced. The W&D logos were stamped into the wood in the throat area. By 1883, the tilt was abandoned for the now classical symetric head rackets and by 1885 the oval shaped racket was introduced. (To here.) Grip size: 4 1/2 measured by ruler.
