Kooky, have you thought of trying the Glasgow Poor Law records at the Mitchell Library, a mine of information if your man, or his family, ever applied for relief & most folk did! Mostly destroyed elsewhere in Scotland, Glasgow's are kept in storage & after searching the index the ledgers are brought to your desk on a wheelbarrow!

I found a claim by my grandmother, my grandfather was a hammerman in the Caley, Springburn, but took pleurisy & was off work, he received money from a railway scheme for so many weeks then she applied to the "Parish!" That was the Caledonian Railway Works, later the LMS.
Springburn also had Cowlairs, the North British Railway Works, later the LNER, & other works including the NB Loco, the North British Locomotive Works, which made engines for export.
My grannie was awarded a few shillings after a visit from the inspector who wrote in the notes that he will try to recover this money from his father!

Try the Mitchell!
Skoosh.
