I discovered this old shipwrights adze at an estate sale this weekend and am having trouble identifying it.

The partial makers mark reads ---LLER & TOR--- below that reads --OOL MFG and below that is ORTLAND. There is a K forged on the side of the adze which leads me to believe the above LLER is KELLER. I'm also thinking its from Portland ME, not Oregon. I've done some basic research and am running into dead ends. P1010001.jpg P1010002.jpg I thought some of you folks may be able to give me a lead or two.. The cutting edge is 5 inches across and the pole is 2 3/8 inches long.

Thanks much

Jeff
