What a shame, just rotting away. Interesting mounting of the Grote beacon on the front and I guess the TwinSonic's motor or chain failed and it was given Force 4 internal parts.
It looks like this truck was originally equipped with a Federal electronic siren - either a PA15A or PA20A. The mounting bracket for the siren is on the dashboard and just to right of the steering wheel. ALF Pioneer trucks with electronic sirens are rare. Most of the Pioneers I've seen have &@#%$! mechanical Q sirens on them. Whoever restores this truck should put an electronic siren back in it.
