These are the ones from the time of the tsars

D is the oldest: Crimean War 1854/55 officer's hat

H is a marine infantry hat from 1890

B Is a soldier's hat M 1910, which was also worn in WW1.


Then come the Soviets:

J is a cap of the early Red Army 1922 to 1934 (still with the "hammer and plow symbol."

G is a commander's hat (officer's hat) of the infantry before 1943
After 1943 the visor changed and got a bulge at the front so that rain could not run into the wearer's face)



K is the hat of a Soviet marshal after 1943 - the one shown belonged to Stalin, he wore it in Potsdam.

C is the cap of a simple Red Army soldier of the infantry from the 80s.


And the new ones from the Russian Federation:

F is a new style officer's cap, introduced in the 1990s, the red star is now gold and the double-headed eagle emblazoned on top

E is a cap for the police and the judiciary (prison guards), they have a blue-white-red cockade without a star

I is a service cap of the Kremlin Guard (which was reintroduced on December 22, 2000 under Putin)

A is the newest one, the service cap of a register Cossack of the Russian Federation. This "register" was reintroduced under Putin on December 5, 2005 - these register Cossacks are a kind of auxiliary police and can be identified by their blue and white cockade


Cheers

Good quiz Martin. I only picked up on it today. I might have guessed a couple correctly, no more.
I've got one a bit like "G" in the loft somewhere - don't think it's original. I got it from a militaria dealer in Ukraine some years ago.
