Armed Shotgun Choke Question

[Big Uke]

I'm looking for some info on the box of 4 chokes that came with the 19" barreled ARMED shotgun that I picked up yesterday at the Kamloops Gun Show.
There are no marking other than a notch cut into the end of the choke. That's one to four notches to be precise;



I can guess at the chokes by looking at their thickness and weight, but does anyone know for sure?

Thanks.
Great gun show BTW. My first time at the Kamloops event.

It's usually:
1 notch, full
2 - IM
3 - Mod
4 - IC
5 - Cylinder

My guess is that you have one with 5 notches in the barrel of the gun already?

Thanks for the info.
And I can't count !!! Revised photo;



There was a 3 notch (modified) already screwed into the barrel, tightly.

5 should be skeet

5 has always been cylinder on all the Turkish shotguns I've owned. Never seen one come with skeet.

I'll need to smooth out the burr left by machining before I use this one though.

Just double checked my Turks and you were correct. My Canuck is C but the armsan has skeet
