Russian army insignias

[pieand]

Hi everybody,
Are these insignias of the WW2 era ?
Can I also have an idea of the value.
Thank you in advance

All are prewartime semimilitary organizations quolification badge, except one in the center - it's tzarist Russia military badge.

Correct, as usual.

The Red Cross badge is, I think, the 1934-1941 version.
Voroshilov = '32-'41
Aviakhim = '35-'39
GTO = '31-'36

Couldn't find the baby Lenin badge but it looks like 30's era as well.

edit: 2 of the badges have their suspension chains replaced.

Baby Lenin pin is a Young pre-Pioneers pin for children ages 7-10. This group was called Oktjabrjata - Children of October. It's a prewar pin. 'Oktjabrjata are Ilich's Grandchildren' is written on the pin. Ilich is Lenin's middle name. This children group was a pure political group, i.e. has nothing to do with military.
