I just sold my 1947 Custom Super Clipper limo after about 18 years of ownership, and though I am not an expert on this cars, I believe I can answer your question. The part you mention is not supposed to be seen. My car had it black (though it was a black car), and all the cars I have seen also have it in black. The lines painted over the chrome part were supposed to be a dull silver, same as in the rest of the mouldings. I didn't keep any detailed pictures but only general views. I am enclosing one. In case you are interested in looking at them, let me know your email to send them to you. Hope this helps. victor.
