Does anyone know where I can get a replacement part (variable capacitor) for
the Antenna Trim (I think its C77, 100 pf) on the above swl receiver?

I doubt you'll find an exact replacement. Try a local hamfest or
electronics store. Look for something that can be adapted mechanically.
The capacitance value isn't that critical, so if you find a 200 pf cap,
grab it.
