If you decide to make any information on this available to the "Mere Mortals" out here, I would surely like to see it. I recently converted 4 of my 1919s to 762X54R. One of these would fit nicely into the group. However since I didn't even know there was a VZ59, wouldn't have a clue where to start, might well be more of a hill than I am climber!! But I sure do LIKE IT anyway!!!
