So a little while back a picked up a project f-14 in a trade, it was part of a package deal. I think it is a prototype or early in the run. Reason being the flashers on the back row are all clear and the stannd up targets are all green. From what I read on ipdb not all prototypes have the x in the serial number. Are there any other ways to find out if this is prototype or
How early in the run it is?
