Is this correct

[Carlo]

Based on your description I think the scabbard is correct, but the pouch is missing (it should have one).
There are very minor differences with the scabbard, like the lenght of the (end of the) back strap or the markings on the plastic of the web assembly. Why don't you post a picture?
Yes you are correct about the "three" or "four" line.
Keep in mind that this is a definition "adopted" by collectors.
