How far will I get with my 3 D cells?  They make it wind nicely, but I've been 
afraid to try 6V, having read somewhere (probably Brooke's pages) not to exceed 
3V lest one damage something.  Then again, that's the local battery, not the 
setting signal.  (No. 6 dry cell?  Dear me, I hadn't even thought of one of 
those for 40 years.)

Then again, what's a day off for, if not this kind of thing?


Brooke Clarke's pix are nice, but I think I have the nicest SWCC clock out 
there, one of the nicest I've seen.  Coincidentally, I bought it in about 1986 
from a fellow named Clark (last name I don't recall), who was a member of the 
Minnesota horological society, or whatever it's called.  A friend of mine, 
another member, put me on to this, and I jumped at it.  (Actually, he has an 
even nicer one, a big Air Force unit IIRC that's about 6 feet tall, and with a 
mercury pendulum bob.)  Took the thing back home to California, and it came with 
me when I moved back to Minnesota in 2003.  It's been the primary time display 
in my house since I got it.  I also still keep the Textronix carton I scrounged, 
that's a perfect fit, for moving it.
