I've seen some discussion in the past on icon about the Flat top CD 155 Kerr's that i assume are not too common and are listed in the guide. I came across a CD 162 Hemingray - 19 (EIN 120) in green tint. Now this is a variety that has the Flat top and is 3 3/8" tall by 3 1/4" wide. Regular 162 Hemi - 19's are 4" tall by 3 1/4" wide, so you can see its 5/8" shorter. I was wondering if this Flat Top shorter variety is common or fairly rare. Can any 162 specialists weigh in on this for me and i don't see this variety listed in the guide.
