Vintage broadhead identification Help

[bharring]

Hello, I purchased a box of broadheads at an auction and have been unable to identify the broadhead in the photo.  The broadhead is 1-7/8" long by 1-1/4" wide and has a slot for an auxiliary blade, there are no manufacturers stamp or markings on either side.  The other broadheads in the box were a mixture of Bear, Herter's, Hilbre, Arrowmate and MA3, so this broadhead may be from a similar time.  This is my first try at attaching a photo, I hope it works.  Thank you

Thank you.  I liked the look and construction of the broadhead, good to know the name.  Also, there were a few stainless steel Bear razorheads in the box as well, so broadheads across a couple of decades.
