Thanks 53Moneypit! That was very helpful indeed! What I have is a oil filter assembly from a 53 that needs to go back on to the other 53 just installed. Should not be too hard to figure out now that I know what it is and where it goes thanks to the drawings shown and your referral. The drawing for the 1952 looks exactly the way mine should be and hopefully the oil lines will fit perfectly too. Thanks again!
Best regards, CJB
