Wow, Kenny!
You sure must be living right!
Not only is that a very nice range overall, but the condition of that smooth-top is phenomenal. You never ever ever see the early ones looking like that any more - there is usually a dark spot at each burner position, due to lackadaisical cleaning. Over time, lack of thorough cleaning caused permanent darkening - this is why today's smooth-tops are any color but white.
Very cool find. You need smooth-top cleaner (Weiman's is good) for regular cleaning, and Bar Keeper's Friend for tough stains. As tempting as it will be to just wipe 'er down with whatever's handy, resist the temptation - minerals and food debris in wet sponges and dishcloths will leave a residue you can't see, but which will burn on to the top and darken next time it's heated. It will clean up if someone makes the occasional mistake, but if it becomes a habit, that's when you get the permanent dark spotting at each burner.
Great range, and it couldn't happen to a nicer guy.
