In the past, there has been discussion about when/if "Lunar Lander Feet" were introduced on the RV6 line. Respondents all say that they didn't have that style feet and as I've picked up a couple of other RV6's over time, I would agree that they're at least more scarce. I've chimed in stating that my RV6, purchased used in 1979 through the Sky and Telescope, Star-Gazers Exchange, came with them. This same mount also has the "Declination Slow Motion Control". As I've been going through some of the old Sky and Telescopes magazines, I haven't seen any RV6 ads showing the feet, but the 1969 introduction of the RV8, clearly shows "LUNAR LANDER FEET"! It would seem that my scope came with an upgraded RV8 mount.

I checked three in my RV6 collection. One has both the "lunar lander" feet and the declination slow-motion.  The other two have neither the special feet nor the declination slow motion. 

 

So perhaps there is some connection between the feet and slow motion?  Maybe all scopes came with both the feet and slow motion for some short period in 1969?   Or perhaps both are part of some upgraded mount package?

The upgrade option is what I'm thinking. Never owned a RV8 so it would be interesting to see if those owners are all "Lunatics"!

As a kid, I purchased my RV6 new. I remember waiting months for it to be shipped from Criterion. Has lunar lander feet but no slow motion. It was just the base model, no extras (couldn’t afford anything beyond that).

Interesting... do you remember the year?

I’m trying to sort out what year it was. I think it was around ‘71 and definitely no later than ‘73. This is a photo of the scope a few years later (I was a summer camp instructor, far right looking up). The scope in the upper right was at Pine Mountain observatory they would let us use (the 24” was capturing light curves of Cygnus X1 by U of O astronomers and the 32” hadn’t been built yet, if I remember correctly).

Here is a more recent photo of the RV 6. My son and I cleaned/repaired it a few years ago.
