Help with 50's Mercury parts

[John]

I have 2 Mercury parts, new in the boxes, looking for the applications:

 

!st is a cable with knob, almost 6' long, part # FTD-7001890-A.  

2nd is a chrome molding, casting # BR-16161-A, that looks like the one on 53 or 54 front fender.  

 

Would appreciate help from anyone who has parts books and can make positive ID.

That FDT prefix doesn't make a lot of sense to me but for 1957 Ford there is a B7A-7001890-B that is a cable for a vent. My 55 Bird has cables that go out to a vent flap inside a tube above the front wheels. Mine is a push-pull cable but the one you pictured looks to me to be a knob to be turned. I believe it is from the mid-fifties era and is a vent cable.

 

My experience with Ford parts is that the first letter in the prefix denotes the decade. Letter "B" is for the fifties, letter "C" is for the sixties, Letter "D" is for the seventies. The second character (digit) denotes the year. A part for my 73 Mustang started with "D3". Parts for my 55 Bird start with "B5"

Thanks for your response.  Mine is a push-pull with a little more than 1/2" travel. Since the box is for "styled accessories" I assumed it related to some add-on item.

The Ford parts use that code except in the big trucks it gets a little different.  Mercury and Lincoln codes in the 1950s are a bit different and I haven't quite learned them enough to know at just a glance.  In the early 1960's they got in line with the rest of the Ford codes.
