Chimney identification

[FarmerBob]

Hello, I'm in the middle of a remodel and need to extend my wood burning fireplace chimney. I am having a hard time figuring out what brand it is and if there is anything I can buy locally that is compatible. The inner pipe is 8" diameter, outer is 12" diameter. Fireplace was installed new in this house in 1990. See picture below. Any help identifying the brand and websites that might carry compatible chimney would be greatly appreciated!

I can almost guarantee the chimney is out of production

It looks to be air-cooled and perhaps not up to UL 103HT 2100º standard?
