combination in the study for sherlock holmes.

hi there guys, I'm stuck in Sherlock Holmes in the study, there is a combination and i have went through everything and i cant seem to find it. i have tried dates in the fake and real register and still not having much luck. i would be greatfull if anyone can help me on this. thank you in advance. regards :)

is there even a hint that anyone can give me? maybe am just over looking something? thank you in advance :)

You could read the hints in the game.What are you're options?

I'm out of options, was hoping someone had got by this stage and knows what the combination is. its a 4 number combination, and i have tried everything in my inventory, dates etc, but no luck.

I've played it but don't remember the combination since I moved on.When you press the right side shoulder button it let's you look into the hints
Or when in the item screen tap the ? button on the right side bottom of your screen it goes to the hints screen. Tried that?
