Ron, that's not a '55. The '55 Polar is a semi-recurve with a one piece riser. Most fo the 50's Polars (and the 1960) have the red glass ('53 on at least... have to check the earlier catalogs when I get home). I have the '55, '56, '57 and '59 Polars. Love every last one of 'em. Still on the lookout for the earlier Polar (reflexed longbow) in the 50#+ range.
