In the lobes we map fast moving knots of material with [N II]$\\lambda 6584$/H$\\alpha$ ratios up to 12, and with radial velocities relative to systemic from -340 km/s up to +390 km/s. We find evidence of a bipolar ejection event at a velocity $\\sim 600$ km/s from the central star (assumed to be a binary), which occurred about 8000yr ago. The fast moving material is chemically quite distinct from the lower velocity gas in the bipolar lobes., and displays very high N abundances. We","authors_text":"A. Ali, A. I. Karakas, D. Goldman, M.
