Gert,
Sorry, I do not have any pictures of that plane. It has been a long time since I flew mine, it is since long gone. However, I do remember it being tail heavy as you stated. I do remember having to add weight to the nose to balance it. If my memory serves me right, I remember this plane being on the heavy side, say around 9 lbs. I wish I could help you with the C.G. question, but I can't remember where the C.G. is. I wish you luck with your new find.
Check out this link, it may help you.
