I too have a flannel cover for an early 28 ga. case. It is fragile (ripped) so I replaced it with a canvas cover I bought from Kenny. Much nicer! My other 'odd' cover is for an early 20 ga case. The zipper is centered top to bottom and is continuous, instead of being closer to the top and split in 2 parts, as on my other covers. I'd take pics, but I'm down in AZ chasing doves and quail
