How can I find the c/n of this plane or any...

...similar plane for that matter?

Obviously it is going to Transavia but, the frame just left Renton (factory) for the first time and landed here at BFI without any other numbers but the test/ferry regi. According to some sources on-line, it could be PH-HSF or PH-HSG although I assume it will be the latter since the other one (F) is claimed to have first flown in January...

Regardless, my question is, is there an official record somewhere or some other way to find out for sure what this bird was/will be?

Taken on Sunday April 1st 2012 at KBFI after it took off from nearby Renton, touch and go at KPAE and then to BFI for final touches.

Thanks all for your expertise.

Planespotters.net has a pretty good production list, which includes planes that haven't been delivered yet, and sometimes includes the test registration.

According to them, the next 737 for Transavia is PH-HSG, and it's due for delivery in June.

You ask Manny, I deliver ;)
