McCulloch Super 44 Bar sprocket question

[jeepstrapped]

My son picked up a McCullcoh Super 44 saw at a rummage sale.
So far we rebuilt and tuned the carb, did some light cleaning, and now he has a running saw.

The question:
The bar is a 24" McCulloch bar. # B066172
.065 gauge and 7/16 pitch.

Does anyone know where to pick up this bar and chain?
Or,
Does anyone know which sprocket and bar would work to change it to a 3/8 pitch and .050 gauge? Or anything else that is more common to find.
