"We've just re-branded ourselves in the last few years that we're the 'can-do company'.
"The reason for that is that Dad couldn't buy something so he made something. And then [purchasers would ask] 'can you put a set of forks on that?'"
Alex says his father's reply was always, "yeah, we can do that," and it's become his son's, and his company's, mantra too.
"That was back in the late '60s and here we are, we're still saying the same thing. Someone comes with a problem, at the end of the day that's what we are, we're solution finders," Alex said.
Alex is anxious to pass on to younger generations the lessons he's learned and his wife Catherine Quinn was on hand to acknowledge his efforts.
"It was interesting with Matt, who called in, another ex-employee of Quinnie's, who had had an apprenticeship, and he said that the one thing he remembered most from you [Alex] was, 'before you start a job think it through,' and he just said that he'd thought about that so many times," she said.
Mrs Quinn was initially attracted to her Mr's smarts, values and dedication to others. "The word to sum Alex up is selfless. He has put endless voluntary hours into our community," she said.
At the close of Alex's 49th exhibition at Fieldays, Mrs Quinn inconspicuously loaded up the crew's remaining home-made biscuits (yo-yos and Anzacs) for their last visitor while saying to her husband, "I'll make some more at home for yah hon'."
Unperturbed Alex replied, "oh, it's fine," as he took a puff of his Peterson pipe.
