    I picked up this cowl vent with some Model A and 32 Ford part. It measures 5”by 11”, does anybody know what it fits and the year. Thanks for the help. IMG_6157.jpeg IMG_6156.jpeg

    Yes it usually is a great source of info but after 3 1/2 hours and not even a guess? Maybe all the smart folks are in bed

    We can narrow it down a little: it’s not Ford.

    I've had functioning Dodge (and Plymouth) cowl vent doors and linkage back as far as the 1939 model year, If that is a Dodge (or Plymouth), its older then any I have seen.

    Looking at the size and heft of the weight of the actuating handle, its possible its from a big truck, the time period from the late 20's to early 30's when such items were over built and built to last a life time.
    The two pictures shown here are purely for illustration, these trucks are too new, in regard to the cowl vent that @Lonestar7778 is inquiring about.
    Everyone's results may vary greatly!
    Thanks from Dennis.

    The red truck shown is a 51-53 Dodge 2 ton, and the green CEO is a 54 & early 55 Dodge. Everything on or in those cabs are the same set up as Dodge used in the pickups, and is the same cowl vent used in my 49 Dodge pickup and is very similar to what was used in the 39-47 Dodge trucks. The Dodge (and Plymouth) cars and trucks from 1939 on used a lever with a spring and roller bolted to the dash to lock the cowl vent closed and had a separate rod connecting the lever to the vent door and the Mopar cowl vent door is also different, no V in the bracing on any Mopar cowl vent door I've ever seen (including the 35 Dodge I had).
    Mopar, at least after 1935 did not have a cowl vent door and linkage like what is shown in the original post.

    It isn't a Model A part. They had (on some sedans) a left side vent. Remember, the gas tank is in the upper front of the cowels on all Model A's.

    I would think the air deflector/router would be the giveaway.
    I've never seen one with

    If I were forced to guess, I'd go with the same thought of something commercial. I'd 1st thought early, like 20s perhaps. But the plastic knob says later, and it must be better than the 1st stuff used in the late 30s thru early 40s since it still looks ok and not all mullered up. Postwar truck of some kind, the inner structure designed to push air at the driver and p***enger floors. And, as we all know, probably a Dodge truck at that;)

    Hey, @VANDENPLAS , in today's vernacular we gotcha brutha:cool:

    Hey @Lonestar7778 , just out of curiosity, put a magnet on the round ball knob to see if its magnetic. To me if that is a type of plastic, amazing how its not crazed or cracked, considering its age.
    Thanks from Dennis.

    Update… The knob is metal and not magnetic, has small cracks and look to be painted gold originally. I did find the base the door fits in, the only marking I have found any part is a letter C on the bottom of the door. Thanks for all the comments.

    I’m thinking that is from an early semi tractor?

    Looks closer, just to the right of the stamped "C"-- there appears to be a "6" and a few more numbers after that?

    With that center hole that has mounting screw holes on either side, I'd guess it's NOT a side mount but top (cowl) mount using that as a drain.
    Fairly crude/basic, since it pivots outside the opening, so more slots to seal unless it's right up against a vertical windshield. That would block a swing out windshield.
    Also with the ball handle being part of the casting.
