Help with authentication of WW2 Royal Marine Blues Uniform

[Tonomachi]

I was wondering what the membership thought of this uniform (see photos). It would be easy to add the bullion combined operations patch to an original uniform thus increasing its value. I know next to nothing about WW2 British Royal Marine uniforms. The only photograph I could find of someone in a Royal Marine blues jacket with a combined operations patch (see photo) has it sewn on the left shoulder not the right shoulder as with this uniform. In addition the combined operations patch was usually worn in pairs with a right and left facing so they pointed forward. This bullion combined operations patch is facing backwards. There is no provenance what so ever. Any ideas as to authenticity?
Thanks in advance for your help.
