You need a copy of the owner's manual for your rifle- trust me- parts of the bolt are tricky. You can get a copy for free from Winchester is you are in the US. The link below will take you to their order form on their website.
You need a manual. Contact Winchester or find a gunsmith and ask for help.
don't take down a Winchester model 52, the way they bedded the rifle was a mystery. It may never shoot the same if you take it apart.
You should be able to find a assembly-disassembly guide for your Winchester model 37 on E-bay.If not you may to need to visit a qualified gunsmith.
Request a manual from Remington's web site.

If you pull the trigger while pulling bolt out does not work . Then you take the big screw out of stock now with the barrel and stock apart , take the screw out of the trigger . With the trigger out of the way you will notice a piece that is the only thing left other than bolt , push on that small piece while pulling bolt and there you go . It will take less time and easier than for me to typr this out lol
The Remington model 700 bolt handle is part of the bolt body and this is a one piece forging.The only way to remove the bolt handle is to cut it off at the bolt body.
I'm not sure how you take the bolt itself apart but if you are looking to dissasemble it to clean it all you have to to is hold down the trigger and open the bolt as if you were opening it to load it and just pull it towards you and it should slide right out. There is also a screw on the bottom that can be unscrewed with your fingers. When that is unscrewed the barrel can be removed for cleaning

Need to know who made it. Need to know if it is a bolt action, pump, or semi-auto. Does it have a model number on it?
hit it with a hammer
