Need HELP on if this is a P-38 part???

[Mark 54]

Hello I am new to this forum and was wondering if this may have been part of a P-38J?

 

[FLYBOYJ]

are there any markings or numbers on it?

Sorry,No part numbers.

The dimensions of this part are 1.055 m x 0.475 m x0.04 m.( 1 m = 3.38 feet)

looks like an access door of some sort....and just looking at images i do not see anything like that on a lightning...doesnt mean its not...

What's amazing is that something that big doesn't have any markings, no?
