Thanks John, I am looking forward to  the pictures to determine if it is the same one.  Sorry about the delay in answering.

  The horn ring that I have isn't the same number as your stated.  Mine is 1138543.  I don't know if this one would fit or not.  Sometimes they superceeded part numbers and they were one of the same. I will try to take a picture and send it to you........John

Sorry it took me so long to reply.  If you would be interested in selling it I might be interested in buying. 
Let me know including price.  Thanks for the reply

Ron

I might have one, but it is back in Maine.  I am in Florida until the first of May.  If you don't find one conact me sometime the first of May.  I know I have one on the wall in my Plymouth Room at home, but don't know exactly what year it is or the number on it.  I know its got the gold Plymouth ship in the center.  Chrome ring with slots going up and down in the sides of the arms that connect to the horn ring itself.  The one I have is not perfect, but pretty good.  A few small pit places........But all in one piece and shines pretty good.  I have kept it for a wall hanging.    John

I have a 1952 Cranbook 4 dr sedan.  The horn ring is broken and the part I have left has the number 1325170 on it.  I would like to have this part,  My car is not a show car but in process of becoming a driver.  If you have one of these you can part with please let me know.
