I've recently added to my BSA album some Airsporter instruction and maintenance sheets, plus some advertising literature.
Here's a direct link to the main album from which sub albums can be accessed:

There may be more to add in the future as I go through the many files and folders I've accumulated over the years.
Many of the originals are still in my possession and will be disposed of in due course, so if there are any of particular interest to other BBS members, please drop me an email.
