Very Specialist Knowledge Sought

[Alex1890]

See attached image. Although I cannot be sure, I suspect the man was in the Middlesex Regiment, with the image dating from approximately 1918/9. The aim of my project is to identify him, but I need some help to confirm key information to help me get started.

Lower right arm appears to have five overseas service chevrons, including one for 1914. Lower left arm has one wound stripe and two Good Conduct chevrons. I take these to suggest that he was probably a pre-war Regular soldier. Is this correct/reasonable?

Above the Good Conduct chevrons is a trade badge. Does anybody recognise it? If so, any information would be appreciated.

The man has a group of medal ribbons. Does anybody recognise them, or suggest what they may represent?

With your help, I may be able to put a name to the face, and tell his story.

Thank you in anticipation.
