I have 3 different Patrone 318 rounds. I have the standard S.m.K.H.Rs.L’Spur; (TEAR GAS/TRACER WITH TUNGSTEN CORE) with a black bullet tip. I also have a TREIBPATRONE 318 FUR GEWEHRGRANATE (HELLES HOLZGESCHOSS) with a short natural wood bullet. My third round is, I think, a PATRONE Ob.
1–What does “HELLES HOLZGESCHOSS” mean?
2–What does “Ob” mean? Does it stand for “obungsgeschoss”? And if so, what load is it? Mine has no bullet tip color and the bullet looks a lot like an s.S bullet. Primer seal is red.
3–All three have headstamps with P or aux WAa year ## (lower case letter). I assume the 2 numbers (##) are the lot number, but what does the lower case letter designate. I have the following headstamps:
P Waa700 40 14d
aux Waa109 41 53d
aux Waa364 42 14f
