GLF Model 390

[markdd]

HI, I just purchased what appears to be a rare Grange League Federation (GLF) model 390 AM/SW radio (1948) and I'm looking for a schematic. There's very little info about any of these radios on the web as they were only sold to GLF members in up state NY back in the 40's-50's. I believe they were manufactured by North American Philips (NORELCO) for GLF and sold as OEM with the GLF emblem on the front. These radios have additional tube circuitry to make them more sensitive as the GLF radio station network transmitters were very low power. Anyone know where I can get/buy a schematic?
