Compatibility with PA800
The problem is with the compatibility of PA800 with the PA802 and PA803 sets. The arm sockets on the marching soldiers are too small to allow the instruments to get a reasonable surface to complete a solid bond for the glue. Filing the arm is difficult on the instruments. The Standing Soldier works perfectly well. The problem that I see, is that the shoulder sockets in PA800 are significantly smaller on the marching soldier than the standing soldier. This means that while the band instruments and arms from PA802 and PA803 fit the standing soldier with a little work, it is almost impossible to fit them to the marching soldier even with heavy filing. The heavy filing is impossible on the "Large and Small Brass" without damaging the instrument, and the flute and clarinet are too flimsy to allow major work.
