Hi, Dan
Greetings from the hoooot Southern hemisphere (namely, Brazil). I've been expecting someone to answer your request but as I see you are still empty-handed, I decided to take action.
I'm a long-time PAMPA member and happen to have the article you want. By the way, it is in my "to build" list (along with about a hundred other planes). I also have the full size plan and some other miscelaneous tidbits on the model.
I've scanned the article for you but I'm not sure how to post the scans here. Give me an e-mail address and I'll be glad to send the material to you.
My e-mail is ferenc_zamolyi@uol.com.br.
Regards
Ferenc
