Will,
Woohoo! Thanks for the additions. I was hoping for some input on the cut-off date. I asked for suggestions in post #1, but there haven't been any responses. Surely, there are some opinions out there on this matter. Wolfgang Matt and H. Nishioka's Opal and Opal II are the latest planes on the list, designed in 1995 and 1996 respectively. I have yet to post the images in the image-base because they do look more modern than classic.
Do you have any specs for the planes you submitted?

Thanks again!
