David.... Thanks for straightening me out. My Mooney Alon was S. N. 281, one of the last. So apparently this cabin air system was used only on the M-10's and a later few of the A2A's. It used 1 1/2" tubing, I believe, and had two outlets on each side in the cabin. Seemed to be a well-designed system. As
I understand it there never was a parts manual for the Alon A2. Best Regards Cliff....
