    APU Switch supplier

    Hi all,
    I would like a better (more realistic APU switch for B737). The Boeing part number being 85-129[H] (or equivalent). Does anyone know a source or supplier for a replicate or second hand switch or close enough production switch?
    Thanks
    Jason

    The Honeywell 1TL1-5M is the closest I've come across for the NG APU Start switch.
