From the former chapter adviser at the time, Carroll Palmore:

This is not a private issue. It is a historical chapter issue that was issued by the Baluga Chapter of 498 in 1985 as a fund raiser for SME. The patch was ordered by Ed Zall (the DE for the Philippines) and made at the same location that the original Baluga flaps were ordered. The sky color was changed to distinguish it from the original. A second very limited issued with a darker yellow sky was given to to chapter officers.
