Help with Swedish silver flatware

[turtlegirl]

Hi - thank you in advance for any help. 1st time here. I have the following silver set and need help figuring out where its from and the markings. It says "JERNBOLAGET ESKILSTUNA MADE IN SWEDEN ROSTFRI"

I can not get a clear picture of the stamp, only the names, but it definitely has an 833 and an M

I have a full set of this (12 place settings, 11 piece per set and 19 serving pieces!)

The mark image you have supplied is a cutler's mark and only applies to the stainless knife blades. You'll need to provide a mark photo from a fork or spoon.
