Huge 38x22x26 flat top travel trunk

So the obvious is this is a beautiful very large automatic open flat top travel trunk with all original parts. I will replace the leather straps of course. This was given to me by my great grandfather who said it was a NM Secor trunk. What confuses me is the only label on it is the black and whit pic I posted and it appears to be St. Michael as you can see walking over bodies. Can anyone elaborate on this matter??
