37 Pattern webbing with white thread

I got these pieces in a massive mixed lot of Belgian and British webbing and I'm not sure what these are.

Looks to me like in service repairs, they just used white thread on the sewing machine instead of a less obvious colour, maybe on the thought process of they were stitched on the side you wouldn't see when its being worn or that at some point Blanco or other forms of webbing paint would've been applied covering up the colour of thread used.

Thank you, I wasn't sure about the green brace. I've never seen green 37 pattern, that wasn't blancoed green. Any information on why the brace is made of green webbing?

The Belgians made their webbing in green, maybe it's a repaired belgian brace?
