Anyone that is alive today that knows or has a true idea that they know....my guess is we'll not hear a peep from them and it would be wise or the copycats would be flooding the market with "Buska tributes" with the foil look.
My other guess is this and only a guess because this is what creative minds do.....
I believe George saw an inexpensive decorative foil that crossed his path and he thought to himself "it would be very easy to hide the ends with an overlap of this stuff at any length cut on a round object" and the rest, as they say, is history.
It was probably on a gift box lid he saw that was already used in that fashion only on a much larger diameter than a cue.
That's my guess thrown in the ring..........
