I've known about this case for years.
I should have specified that the internal length be at least 40".
Outside dimensions: 38.12" x 16.00" x 6.12" = 60.24" That is within the dimension requirements. If only my carbine barreled TM1000 rifle (39") could fit the 35.75" length interior length. Mine is about the shortest TM made. And no, it's not practical to take the rifle apart, as I need the room for the pistol, too.
My CZ200s rifle will fit fine, but I gave up that rifle two years ago. I'm not sure there are many other rifles this short to make thie 1700 Pelican useful.
