These are some of my oldest cases. Each side is roughly 3'x3' and has a hinged door that has a lock. Very time consuming and expensive to make. A little heavy and awkward to carry and transport. The arrow clip arrangement inside is very poor. I should be beaten for not improving this before now.
First the clips should be on a 3/8" thick wood strip so the 4 blade heads do not have to be turned at an angle and sometimes angled forward.
Second the 1-1/2" spacing between clips should be staggered between rows to permit the longest heads to protrude into the space above.
Several of these old cases still need to be changed over to have the staggered clip arrangement, which is an improvement that has become widely accepted within the past 20 odd years.
The hinged door wastes a lot of space around the edges. The legs also waste space at the bottom. Another row could be added by eliminating the door and expanding the case to the bottom.
As you can see in comparing these cases to Raghorn's, his cases utilize the same space far more effectively.
