I noticed this as well. I've been trying to collect original scans for my upcoming online archive. I've tried to contact JimZ to see if he minded sharing the data on his page to expand mine. Especially since his site seems to have fallen by the wayside.
What about Shasta? Shana? I ended up there once, can't now remember.
I have saved most of the face cards and instructions from rockets I have built over the years.
Please... Scan them. You never know when they might be useful for a BAR.
It looks to me like somebody simply copying online PDFs and burning them onto CDs.
He's making some side bucks off the Estes, Jim Z and Old Rocket websites.
He's even put a Copyright with his name (Clark Ward Orange) on it!
