A very rare Boeing 737 six pack recall unit in excellent condition. This unit is found next to the master caution and fire warn indicators on each glareshield of the captain and first officer. This unit is as removed, but would make an excellent piece for your simulator. Perhaps a restoration to working condition which should be possible with modern input cards, this is helped hugely by the wiring diagram printed on the side of the unit.
Another piece which is likely to sell fast, we only have 1, when it is sold - it is gone!
