Help needed on manufacturer of new pipe wrenches

[Danks]

A couple of new pipe wrenches and swing bar - possibly from a drilling rig. There are no markings on either wrench to indicate manufacturer, model etc. Any help in identification would be appreciated. Swinging bar appears to be home made, but i could be wrong on this. Cheers Danks

New to me, never seen anything like that before but I have never worked on an oil drilling rig
