Strictly speaking, Al, the 419 is GSA 249 (I think, I'll have a look when I get home), but BGA Comp no. 86. One in which I spent several happy hours. I last saw it on top of the Mynd, still in the trailer we built at Yatesbury in 1964. The Oly 2 is comp. no. 134, in which I flew my first competition, and adopted the competition number when I became a private owner.
