Brent, your results look great. From my experience with several Allegros their chrome does not fare very well over the years. Most of my Allegros which have been California finds with coastal exposure plus long term garage storage have extremely damaged chrome. The blue smoke Allegro belonged to the 'little old lady from Pasadena' who took exceptional care of it until her death. I was fortunate to have purchased her bike as well as her husband's 1965 Allegro which was in excellent condition.
Thanks for sharing your progress with the forum. Be sure to read the history behind Allegros.
