Default Estes Prototype Motors Part 2

With the change of ownership at Estes, there has been discussion about possible new motors.

Higher thrust 'D' motors have been mentioned and variously referred to 'D40' or 'D48'.

Well, some were made and I expected they were tested.

My collection contains D48-0 and D48-6 black powder motors.

They are 24mm in diameter and 89mm long (Same as the CATO plagued E15 motors).

I don't have any other information on the motors.

Pictures below are the D48-0 and D48-6 motors along with a D12-3 motor for comparison.
The picture of the nozzle ends of the motors is pretty impressive.
