This has been in my garage for years and I`ve never been able to identify it so it that can serve a useful purpose.
Combined wise heads may help with this.
90 deg. adapter.
Bolt holes are 2-7/8" centers, studs are 65mm. centers and 5/16 UNF.
Bore 1-3/8" in the body, flared/relieved at either face end
Face to face is 1-1/8"
Thanks
