Mysterious Swedish 'M90' Coverall

Coverall in Swedish 'M90' camouflage. I've tried to look for any informations, regarding this piece, as 'Pilot' like coveralls are not usually a commercial made product.

However, I cannot find any information about this piece, But I highly doubt it's 'commercial' due to nature of the suit and how well, it's made, might be some old sample for Swedish AF, that was never implemented in wider-scale. 

• One chest pocket, Two arm pockets.
• Pocket for a map, with additional pockets on hips and shin.
• Manufactured by 'Rory Production AB' in Boras, Sweden. 
• 50% Polyester, 50% Cotton.
• Padded shins.
• Most likely intended to be used by Pilots/AFV crewmen.
