Bought these at auction last week because they had a patent number and I hadn't seen any like them. As you can see Iv'e titled pictures ouch,ouch2, and ouch3. I wonder why? For those of you with patent savvy please wait two minutes before identifing. Well you don't need patent savvy,just be able to read a pat number. These might be available if you run a working ranch.

 Anyone recognize the maker logo? Oval in a circle in a star. Has some letters in the oval but I can't make them out.

It carries a rather hard name, but is used in creating steers. 

Several Saturday's a year as I was growing up I got to see them up close and personal.  The last I recall them being used was in the early 80s by my g'pa.

Rocky Mountain Oyster pickers.....

Patent was assigned to Western Instrument & Manufacturing Co.,but find no info on that company. I can read (MG) in center of logo. Could it be (WIMGC)? Suspect this might be an old company as stationary jaw is 1/2 thick steel and they weigh over 5 lb.

Western instruments & manufacturing .. filed a trademark in 1925, and was sold to the Colorado Serum Co around 1961.

The trademark is pointed on top, but the picture is cut off :(

On these pincers, are the upper and lower jaw flat, or sharp?

 Jaws are not sharp. Intended to sever seminal cord without incision.

Note that the words 'without pain' do not occur anywhere in that sentence....

Thought they would be flat, painless and bloodless if I recall.   If not satisfied just come in for a free demonstration!
