I am sorry to report that Padbury aircraft has been lost in time. This is critical to me because their Defiant and Battle are used heavily in my Early Europe campaigns.
To preserve their files, I need all of you to comb through your archives and see if you have the downloads in their original form. Then we'll see about uploading them here for preservation.
Here is the old site via the "wayback" machine so you know what you're looking for.
Your help is always appreciated,
