I'm not trying to hi-jack this thread, but while we're speaking of 100-4 grills, I've been looking for a straight, undented, and complete unit for over 6 months.
It is OK if it needs plating, but it needs to be straight. Of course an 8 or 9 would be OK too.
If you know of one, please let me know.
Now back to your thread, already in progress....
