Well folks, the jury has rendered it's verdict. Three prominent local authorities called for the opinion of another who they felt was even more of an authority. This is the conclusion.....
"Even though the bill seems small and short (perhaps the angle), the wide dark streaks on the undertail coverts suggest a Common Redpoll. Also, the extensive unmarked white areas on the scapulars and face are not typical of either redpoll. I prefer albinism as you suggested in this case and leucism for washed out birds, but now both conditions are termed leucism with albinism reserved for pure white birds lacking all pigments including in the bare parts. You may remember an article about these distinctions in Birding several years ago."
Most of you folks seemed to be on the mark.
