47-55.1 Weird Title Number (Serial #)

[damnyankee36]

I am looking at 1950 3100 with a missing serial # tag. The title that allegedly belongs to the truck shows the VIN to be 0035556T55X.

This obviously isn't the correct format for the serial #. I read that back in the day the engine serial # was sometimes used. This number also doesn't match the correct format for engine numbers.

Any ideas as what this number is? As it stands there is no number on the truck that matches the title.

I think I would rather go through the trouble of getting a new title with a new assigned number than get one of those repo tags and stamp that funky number on it.
