In fact the real dimensions are 7.8 * 34.9
From left to right :
Brass case Cn bullet, VE 48 C
Brass case, CN bullet, no hstp
Brass case, CN bullet, red tip, no hstp
Brass case, CN bullet, red tip, VE 48 C
The CN red tip no hstp is not a tracer.
Painting was added because bullets were coming from another manufacturer (see Barlerin book on French experimental bullets)
The tracer is the right one (hstped VE 48 C).
This time I will tell you which one is the scarcest !!
It is the tracer.
Some boxes of regular (no colored tip with VE hstp) has been found.
But no box of tracer.
Very scarce round.
