Marked but Im not sure of the maker.  See front.

LARGE...4 1/8" tall and 2 7/8" wide.  Usual wear for an antique lock.  Patina as seen in pictures.  Logo stands out on door.  No key.

GOOD CHANCE FOR A COLLECTOR AS THIS HAS A FANTASTIC LOOK ABOUT IT.

I WILL BE LISTING SEVERAL ANTIQUE PADLOCKS OVER THE NEXT FEW DAYS.  PLEASE SEE MY OTHER LISTINGS.
