Please look at all photographs and feel free to contact me if you would like additional information or a more detail picture.
These are 5 M. Klein & sons needle nose pliers and I believe one is called a duck bill..
These are all stamped with the company logo.
One appears to be grind down but the cutters on all of these are still crisp and sharp.
Unfortunately I don't know very much about these they were purchasing the largest estate sale they came all in a box.
So feel free to ask me for more photographs or specific areas where they might be numbers that I'm not seeing.
Thank you for looking.
