I have an HSI, AI/Flight Director, and a Magnetic Flux Detector from a Century IV for sale. All were pulled out of my Baron for an Aspen install. All were working fine as removed. The HSI and Flight director are not original to my plane, but were purchased within the last two years to replace failing instruments.

Flight Director 52c77
HSI (slaved) 52D137-1333
Flux Detector 1B495

These are really great to have around as spares.

Asking $1000 for the whole package. I'd prefer to sell it all together, but I may be willing split it up.
