I don't think that Crombie is that old. That tag is pretty recent. I don't have a chronology of their tags, but I've seen that one on more recent pieces. It doesn't have the royal warrant, so it's not current label, but I think the really, really old stuff says Crombie Kintyre.
Gotcha, there is obviously no union tag to go by, so I was just taking a guess. On another note, here's a large piece of Brooks Brothers luggage from the 40's. This I did find information on in regards to the metal tag near the handle.
