Good gosh! do these old threads ever pass on to thread heaven?
Why are you writing ? college ? or possible article? If you quote me I would appreciate - No demand - be giving credit for my contributions to your effort. ( I have had it with all the plagiarism one person should have in a life time
You are a tad late, Dick Bonin who was the co-founder and president of SCUBA Pro prior to being sold to Johnson Wax passed away a few months ago, Dick was a dive professional and a much closer friend of Brownie than I so he possibly could have had the answer as to what became of him.
I suspect with a degree of certainly that he walked away from the dive industry never to return as an employee or a consultant . He just disappeared never to be heard from or seen again.
I some how recall he was a WW11 veteran , therefore If alive I would suspect he woukd be in his 90s .
I fear Not much help but you are just a little late,
