I Found the frame and refurbish and rebuilt a racing bike. It was unindentified for last 3 Month. I Need to confirm that this bike is . 1970s Motobecane Grand Record with Professional Nervex lugs . 531 Tubing.( Refer to Origami night lamp 1970 Motobecane Grand Record. The frame and lugs is same as mine.

Early 50s is a starting point, as it looks like it has the earlier Nervex Pro lugs with the central horns rather than the fish tail.

Look for a number on the rear dropout, seat cluster, steerer or stamped in the BB shell. Have a root through the frame builders section of Classic Lightweights to see if you can id it from the frame number. Unfortunately, it doesn't have any distinguishing features that would identify it as a particular builder.
 
Are the bottom bracket threads French size? I would imagine a Motobecane of this era would be?
 
Re:

The frame has an early 50's appearance, perhaps some sharp close ups of the details might help.

If the seat tube is 1 1/8 inches outside, the diameter of the inside might help identify whether it is 531 or a light drawn tube.
