That is intresting,you have so many sourses in Amerika so you kan tell the whole story.(As you kan see in the ser.nr.list there is not so many hammers in the beginning).But from what i guess 1908-10 it start whith AJ Aubreys lockpatent.The frame are different( Meriden and Aubreyframes and Gogh was the engraver on both locks flying "turnips") but the barrels are the same don`t you think.( But AJ Aubrey put his name on some hammerlesslocks too)
