I'm a bit of an aviation documents kleptomaniac, and after pressure from the office manager and wife respectively, most of that has been scanned and then the paper recycled (or donated to the local university library)..
I can do you a full scan of BCAR Section K issue 7 from 1992, or BCAR Section D issue 2 from 1951 if either are any use to you. if you have an interest in lighter aeroplanes, I've issues 3, 5 and 6 of Section S and various electronic copies of versions of JAR, CS, and FAR 22, 23 and VLA, as well as a scan of a 2003 (UK) CAA Handbook for Continued Airworthiness Flight Testing.
If you have scanned the AČEČ handbook, or of the earlier Section K versions I'll gladly swap you. boffin at engineer dot com will reach me by email.
