coach,
I have never heard of a code/marking/ID on a '53 frame (but would be interested to hear if there is one). Of the parts you listed, the rear end is the only part with an ID. Try to find the casting numbers and post themn here. Then, at least the rear-end can be identified, but that is not going to provide a definitive ID of the date of the frame.
What front-end parts are still on the frame?
Tim
