Shooting Shotgun Chamber Length Question

Gallery image

This might be a silly question, but my uncle recently gave me this shotgun and I'm not sure if it can take both 2 3/4" shells and 3" shells or only 2 3/4" shells.

The gun is:

Cooey Model 840 12GA 2 3/4" - 3 full choke Winchester proof steel Made in Canada by Winchester

I've attached a picture.

Thank you all!

I'd feel a lot more comfortable if it said 2-3/4" - 3" instead of 2-3/4" - 3 but I assume it means that you can use either cartridge length (but maybe not lower?)

I read it the same way. Also from my search, it says the 840 specifically is 3". The ones that are model 84 are not.
