Correct Craft Trailer ID#

Does anyone have any information on where the trailer ID # is on 93 CC trailer? The NMMA placard, on the inside of the frame on the port side at the bow, is faded too bad to make hardly anything out. I bought my 93 3 years ago from a gentlemen in Ohio and was the second owner. The original owner was from Michigan and bought the boat at Silver Spray Sports. He said that he did not recieve a title for the trailer and was not required to have one for Ohio. It is the original trailer from Correct Craft from what I can see. I can make rhat out on the NMMA certification that the manufacturer is "Correct Craft" and their is a yellow vinyl CC symbol on the inside frame of the trailer on the starboard side at the stern. I can also make out some of the other specs but not the trailer Id#. It seems that the trailer should have a stamp on it somewhere in the frame with the Id#. Logically, that would be a safe bet due to NMMA tags can be removed and trailers can be stolen.......... The issue is that I live in PA where trailers must have a title to get the yearly registration. I have been using the trailer Id# from my past boat trailer since but need to get this sorted out before someone else does for me.. Any feedback would be greatly appreciated!!

There is a small piece of mirrored tape underneath the tongue but no numbers.. Will try the light trick..
