I was looking at my Prestiges and noticed some differences in lettering and decals between them. The earlier 1984 TXE (first from the top) is darker grey carbon-fiber graphics and didn't have any decals on the frame, only butt cap says "Made in USA". The later version (second from the top) is lighter grey color and does have a decal. Its butt cap also reads "Made in USA". All TXP frames have "Frame Austria, made in USA" written on the butt cap and "Designed by Head USA" on the side. Probably this means that the racquets were actually manufactured in Austria but finished in the U.S. The earlier TXPs (3 on the bottom) have decals saying "Unique tubular ... construction" while the later (pictured below and made before U.S. Prestige Pro) has the same decal saying "EXCLUSIVE HEAD ..." and simply "Head USA". The difference between the latter is that PP was entirely made int he USA at a Colorado plant ... (just like TXE?) Here is the question: where the TXP were actually made and why there, if they were produced after TXE and before Prestige Pro USA (both made in USA)?
