A coil identification

Morning all. I have an A coil that I need help identifying the manufacturer and date of manufacture. I looked on line and cannot find it or identify the company’s logo. It is on top of a Lennox gas furnace:
Model: G43UF-36B-070-04
Serial: 5905C02431
Date of manufacture: March 2005.
If anyone knows, I would be greatly appreciated.
