Here's the Mayhew.  Not sure what the rope threads are yet but do a search on Google and see what you get.

 

Here are listed the common thread connections as used with portable drilling equipment for seismic shot hole drilling, minerals prospecting or test hole drilling, blast hole and water well drilling. Blue Demon Bits are available with the following threaded connections. Dimensions are shown for field identification only and are not for machine shop reproduction.
