Genealogy / Glonski - Polish builder in Canada of RAF aircraft [3]

I am trying to find the full surname of a Polish person, possibly Jewish, who worked for the Canadian Car and Foundry Company in Fort William, Thunder Bay, Canada in the early 1940s. He or she has signed internally one of the wings of our Hawker Hurricane aircraft, a typical thing for builders to do. Problem is that the only readable part of the signature is the last part: '.....glonski'. Can anyone have an inspired guess at the full surname? I am keen to trace the family. Thanks for your help.
