Virgin Aero Ungrade Cowl found and will be the Master for a Mold to make them Available to STC holders..
This will fit 150 D,E,F,G,H,J,K existing metal cowls (just change the nose bowls.
The L model cowl 1971-1974 used a shorter metal cowl and larger nose bowl.
The L model also moved the landing light to the cowl and added a 3 inch spacer.
For the STC the L models must be changed back to the previous years longer metal cowl to use these nose bowls as per the STC.
Note the plans show this cowl in the blueprints.
I have printed full scale drawings and compared it to the prints.
This cowl leaves enough room for final fitting.
Note the prints show adding a metal strip (riveted) to the cowl upper and lower and then riveting it to the existing cowl for final fit..
