[Milsurplus] Identify Dynamotor Canvas ?

[Hue Miller]

I have a couple canvas covers, no markings on them, i 
think are dynamotor covers. Can you identify these?

#1  has rectangular opening flap about 5 x 7 inches in 
one long side, also strap that runs across the bottom,
front to back side.  For PE-103 ?

#2  larger than above, has 2 flaps with zipper close,
one on left upper side, one on right upper side. 

Tnx- Hue M.
