I have the models 611, 613, and 810 which do not have the non-set (NS)
auto stop feature, and I have never seen any of the VivaTonal models that
included the NS feature. Checking the Baumbach book "Columbia Phonograph
Companion, Vol II" I see that the NS feature seems to have begun with the
new line of machines introduced in 1918 and continued thru the "New
Columbia" series from 1924 to 1926. But it seems to have been dropped in
the later VivaTonal and electric series of machines. The NS feature was
somewhat complicated and may have proven difficult to maintain which may
have been the reason that Columbia omitted it in their later models. They
used an "improved auto-stop" feature in the electronic model 920 that was
claimed to work on all types of records, but I have not seen one of these to
tell if it is similar to the NS or otherwise how it works.

Based on what I see in mine (and its cruder ancestor in my Grafonola 75,
1915), the auto stop is a mechanism that works in conjunction with the
motor via levers - a la the brake/stop/start underneath or above the motor
board. It is completely outside the sound reproducing system. It should
not have any connection to / intrusion upon anything from the horn all the
way to the sound box, so it shouldn't contribute to leaks.
Very odd. What model is yours Jim? (btw There's a nice 2-page ad on eBay
right now that has photos of the 1927 models, mine is the lowest end and
is only mentioned parenthetically, haha.) I agree that for Columbia to
omit this in the higher end models (especially if they went to the effort
of using velveteen) is surprising. Do you see anything under the platter
that might suggest there might once have been an auto stop?

My large Viva-tonal (cabinet larger than Orthophonic "Credenza," partially
because doors slide into sides of cabinet)has green velveteen on the
turntable. After the local repairman sealed the horn & rebuilt the
soundbox it sounds splendid even on late 1930s recordings such as Beecham
conducting Mozart's "Symphony in E-flat" with the London Philharmonic.
My
only regret is that it lacks the marvelous non-set automatic stop that
would
cut off at the end of any record. A surprising lack in this next to top
of
the line model. Might this have been because it would introduce air
leaks?

Thanks for the helpful info everyone! (Apologies for the late reply but I
only subscribe to the digest.)
I contacted the youtube poster of the videos that DanKj linked to and
posted on the phonoland board where I'm also a member.
Based on the responses from all three sources, it's Green-land for me! :)
I found one tiny oil stained mini-bumper in the cabinet late last night,
once green, so that confirms everyone's input.
I ordered a Victor sized green felt replacement from Walt @ Gettysburg and
will trim it down to size. I have leftovers from a botched turntable job
on a Grafonola I restored a few months ago which I'll use for bumpers.
Ron - Interesting about the velvet. Apparently they used felt early on,
as in my case, but by the 700 & 800 series Columbia had models with velvet
(I learned this via phonoland.)
Does the velvet help make the records sound smoother? (Just kidding,
though perhaps there's an audiophile who might ardently argue that.)
Thanks again all.

My Vivatonals both have what looks like green velvet on the turntables.
Bumpers look like green felt.
