[cactuswings 2786] Kingman Puzzle

Some may say 'What?? - Only ONE???', but that's all I have so far from a visit on 11th Jan.

Spanair's MD-82 SE-RJH c/n 53165 (c/n 'confirmed' on airframes.org) is recorded as going to N545PT.
One example http://www.airfleets.net/ficheapp/plane-md80-53165.htm
The FAA confirms N545PT as c/n 53165

But see these two shots:-

and

I accept that sticky tape registrations may not be the most reliable of systems, so is the N545PT here wrong?

Or did SE-RJH not become N545PT (Obviously it never got re-painted or stickered anyway)
