Yes, I am he. That plate is actually off my D, I was playing "Musical Plates"... 'kinda like chairs, only with multiple bikes. That picture is probably early '80's at a So. Cal Vincent Rally. The Pedestrian Slicer should be read phonetically. Plan "A" is to put it back on it's original 1938 GB plate. Thanks for the photo offer, but no thank you.
Cheers, John
