RFJ,

From looking at the pictures you provided, the turtledeck and the canopy area are quite different from the 1 to the 1A. The nose area on the 1A looks to be a bit sleeker, not as wide or tall. The engine head on the EU-1 picture looks lost inside the cowl area while on the 1A more of the cylinder and head are showing.

Thanks for your pictures.

Gene
