Tim,
I have what I think is a Bushmaster (Window Bow became the Bushmaster in 1958) that apparently was refinished. There are no logos or labels of any kind on the bow. It has the length and draw weight, but no Cat #, stamped on the side of the handle-5'8" 50@28. It is a 2 piece, offset two color laminated handle (cream and black colored wood), and green fiberglass limbs. Only problem is I can't find a reference to a 68" Bushmaster. According to Archery Archives, Pearson offered a 66" and a 69". I'm wondering if when it was refinished, someone redid the writing/stamp and changed it from 66 or 69 to 68.
I also have a Pearson 950, a 60" 2 piece takedown recurve similar to the Bushmaster, that has the Cat #, Serial #, length, and draw weight, but, NOT offset in the handle. It has a Ben Pearson label on one limb, solid color handle, and green fiberglass limbs. It became the Cobra in 1958. Archery Archives says that the 950 and 954 were "just like the Bushmaster" in 1957 and says they had an "offset handle" in 1958, as the Cobra.
I would be interested in seeing any decals on your bow and seeing photos of them and the handle with the stamping/writing on it.
