Earlier on, and I can't find the thread, someone asked about the GMA AG1 . Here is a photo I took at VSC a few years ago. Hope this is of help to the person that asked about it. 
This plan is available from several of the usual sources here is a short TOC from the MAN is was published in:
Model Airplane News
August 1966
cover - "Rumpler CV" by Jo Kotula
Billy Boy: F/F rubber wakefield by Bill Hartill
AG-1 Duster: C/L Semi Scale Stunter George Aldrich
Spitfire: Detailed drawings by Willis Nye
Shoestring: R/C Pylon racer Jim Kirkland
De Haviland Chipmunk: 3-Views
I don't remember the origional thread either but if someone is interested in building it the above should be of some help.
