<BR>Indeed, as Dennis noted. Note that the chrome lettering on the side
says<BR>"Television" not (yet) "Color Television"<BR>> This camera is much
wider and longer than a TK-41, but with vent<BR>intake holes, tally lamps
alongside the turret, and the profile of the<BR>tube VF of the '41 (but
lacking vent louvers?). Like the early '41s,<BR>the cam shown is using
three monochrome cam cables (were they 28 or 30<BR>pins?), not the 81 pin
connector, that cameras (at least at NBC, as an<BR>in-house conversion?) later
used.<BR>> <BR>> But fitted with a 3:1 zoom, of all things!
(Varitrol? -anyone <BR>> remember?)<BR>> <BR><BR>That would be the lens
with what appears to be a motor on the front and<BR>a cable dangling from
it?<BR><BR>Looking at Bob's picture, it's much easier to see things.<BR><BR>I
think they've done as I suspected: Bolted a bigger plate to
the<BR>standard head, and then run bolts up through the four corners of
the<BR>plate to lock the camera down. Counterbalancing would seem to be
an<BR>interesting challenge unless they figured out where the camera's
center<BR>of gravity was with the lenses and such.<BR>> <BR>> I hope,
like Ted observed, that there were springs in the head. <BR>> <BR>There
are: Close up, you see the springs right in the center, and the<BR>standard
friction tilt lock handle on the camera's right side (as viewed<BR>from the
operator's perspective. Also the RCA serial plate up and to<BR>the right
of the handle. <BR><BR><BR><BR>One has to wonder how easy (or not) locking the

Elsewise, tilt very fwd or back and the cam and cameraman would be<BR>doing a
summersault off the top of that scaffold !! <BR>> <BR>> (I think I read
that the TK-40 itself was really a proto, with perhaps<BR><BR>> only as few
as three serial numbers produced)<BR>> <BR>> (RCA MI-12345? We
