The difference is in the equatorial head, yours is the light weight version, you'll notice yours has the thinner "pipes" and lighter bearings. This was a demand at the time for more transportable compact (F6) lighter version in reaction to the SCT craze. Their full weight mount is about as heavy as the AOS Sampson.
AOS had a sort of similar "compact" 8" F6 Newt, with a lighter imported mount at the same time. Minus the tube rings and quality parts. I think theirs was about $450?
Is there much "play" in equatorial axis when it is in drive mode?
