Russian 107mm mortar projectiles

[MINENAZ16]

Hi,
Is there a different designation for these two russian 107mm ?
I assume the projectile with 5 gas check is from the OF-841 series.

There are/were at least six variants (including the postwar ones) differing in material and stabilizer design. (841, 841A, 841AU, 841T, 841U, 841Sh) Sadly I don't have an accurate drawing showing the details.
