HIATT Padlock

I just received an all brass Hiatt padlock with the original key.  The lock base measures 2 1/2 inches long and 2 1/4 inches in height.   The marking on one side is an "A" and a "B" on the other side.  
No Broad Arrow.  Does anyone have any Hiatt catalogs showing padlocks?  I have never seen one before.

Hi Ron. Page 34 of the catalog which I previously posted a PDF of on here. Dutch padlocks.
I have one in brass and one in cast iron. Paul

Thanks Paul.  The only difference I can see are the markings A & B on the lock body.  I'll have to look for your posting of the catalog.
