Poncho,

That picture was taken shortly after I got the #6 home back in March. The top recess to firepot length for the #6 and the 118 Modern Oaks is 22-1/2 inches from the recess lip that the magazine "hangs" from, down to a line even with the top of the firepot by sighting across side to side.

We now know that the top opening is the same 7-1/2 inch diameter for the Glenwood Oaks, the 116 , 118 Modern Oaks, and the #6 and #8 base heaters.

If you can, measure the same vertical dimension of your # 8 and we can come close on an estimated length going by the coal mound angle.

If this works out and the info and numbers are correct, the larger diameter stoves, such as the #50 Oak (still need to know fire pot diameter of that one), the #8 BB, and the 118 should need a magazine just a bit shorter because, as Franco B pointed out, the greater coal mound diameter. So, they can use the same magazine, but we've yet to establish how much would need to be cut off the bottom of a magazine for the smaller diameter firepot stoves.

The coal mound forms an angle that's relatively constant. Too shallow and it doesn't mound outward - too steep and it continues to flow outward. If we know the angle of the slope, and the length of the bottom of that triangle that is the difference in the radius of the different sized stoves, we can come very close on knowing what the vertical side of that triangle needs to be. That's how much to shorten the magazines for the bigger stoves.
