Thanks for this. In Jim's day, Thornliebank was only about 3 miles or so from Glasgow, so it would be quite possible that a recruiter was in his neighbourhood. Perhaps he knew they would eventually be going to Canada, or some other foreign place, and looked upon it as a way to leave the calico factory? The dates you have so far, and the time he appears to have left the army might indicate such a scheme.
Thanks again.
