Not many folks care for the spiral groove because they're usually so darn plain Jane, but this one's just a bit nicer than average. Good solid green with light amber mixed in. This one was a Brookfield made piece and is much beefier and heavier than it's Hemi made counterpart. Spiral groove itself has no chips or cracks but does have one small bird peck above and below the grooves and one index fingernail sized clamshell from the inner skirt on the rear. Displays perfect, especially lighted. More pix on req. First mail to me...Book is $30 range. My price....$16 + actual shipping.
