Rob,
The bag system is not genuine. The 519 came with a shakeout style bag with emptor which empties through the trap door on the bottom.
Do not use your Kirby G series belt in the 519 unless it has a new style brushroll with ball bearings. The older <span style="font-size: 12pt;">brushroll with sleeve bearings needs the old style soft belt. Using the G series knurled belt will ruin the older sleeve bearings.</span>
