What is the spacing on a row of rivets? Is the distance between two rivets an "even" metric distance or does it come out to be an "even" inch or fractions of inch distance? I assume we are looking through 6 plexi-glass "panels". I am thinking this would be a "top" escape hatch or part of the hatch. Does it appear the hatch was originally "curved" or was it quite flat. It is hard to tell from the photos.

Hi Guy's,

The distance between the two rivets are 1.97 inch
The skeleton is flat, the plexiglass is not originally curved.
I can't find any factory stamp only a nr 3C2038C

You need to measure from rivet center to center. 1.97 in is 5 cm. If that was center to center I would think it was a non US or British plane. If in fact center to center is 2 inches then most likely it is.

From my years of sheet metal detail design for North American and European companies, rivet pitches were rarely even multiples of inches or millimetres. You determined the end rivet locations, the number of rivets required, and then divided the available space evenly. All the sheet metal hand books gave maximum and minimum pitches, but you rarely hit these exactly.
