Could someone identify this furnace please

Front Runner 90 Serial Number 950814016. cannot find a brand name. Only the Gama stick. Age and ID would be helpful.
Are they still being manufactured or obsolete. Might be a good idea to tell the client since he has three units installed in the 1/2 million dollar home I inspected today. He claims there only 10 to 12 years old but I think there older.

A half million dollar home here is an outhouse. Prices here are nuts.
