Mal:@Dieseldoc . . . Thank you, Charlie !! .
Copying is the highest form of a compliment ... right ?
I think I just might do that !! . Or, I might make it a roller ball .
But I'll try to put a clip on mine ( to satisfy the critics !! ) so it won't be an identical copy.
Or I might just do a roll-stop ..... consisting of .... you guessed it .... the "stone" out of an olive !!!
Don't hold your breath, though ..... I don't work fast !!
