Thanks for the tip!  Maybe National is considering a replacement?

If I find one I'll tell you.  At six volts you might get away with
the Telcom TC4426, 4427 or 4428.  Don't believe the data sheet where
it says they will withstand 22 volts.  If you get a spike anywhere
near 16 volts they MORPH into a CROWBAR.  :)  But if you are running
on a battery supply they will probably work great.
