It is interesting but note that the author was not clear on the pipe threads, not distinguishing BSPP and BSPT, and provides somewhat dubious advice at the end about “making do” with UNC instead of the correct fastener. My advice – use the correct threading system and grade of bolt. Note, that despite my earlier tongue-in-cheek comments, the BA thread system is based on metric principles, but with the unavoidable English twist.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif"'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif"'>Cheers, Mirek<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif"'><o:p> </o:p></span></p><p class=MsoNormal><b><span lang=EN-US style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'>From:</span></b><span lang=EN-US style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'> Healeys [mailto:healeys-bounces@autox.team.net] <b>On Behalf Of </b>Curtis Arndt<br><b>Sent:</b> November-22-18 3:46 AM<br><b>To:</b> Michael Oritt<br><b>Cc:</b> John Vrugtman; Healey List<br><b>Subject:</b> Re: [Healeys] bolt identification<o:p></o:p></span></p><p class=MsoNormal><o:p> </o:p></p><div><p class=MsoNormal>John,<o:p></o:p></p><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>Here is some more pertinent information that might help...<o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>I've attached a copy of my 1957 vintage machinery Handbook which shows the various markings used to denote Whitworth from Unified fasteners.<o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>Also an excerpt from one of my yet completed articles.<o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>Cheers,<o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>Curt<o:p></o:p></p></div><div><p class=MsoNormal><b><span lang=EN-US>Error!

So to answer your question... BEES was the vendor. The bolt you refer to with an actual Bee on the head is a very early bolt, and is one that I have in my collection.

The strength rating is "B" and the measurement is 28 to 35 tons per square inch or tons tensile. The range refers to "yield" strength and "ultimate tensile" strength as described in my attached article. FYI, multiply 28 or 35 times a ton and you'll get the strength in pounds, or psi...
