Marlin model 81

[z90HD]

I just bought a Marlin model 81 today (for a good deal). Its in really rough conditon. The stock is busted but repairable,the finish is a dull greyish color and you can tell it was heavilly pitted at one time and cleanded off. The barrel looks great and all the internals look great as well. Now with a lot of help from the wonderfull internet I just about fixed all the ftf and fte problems except for two.

The first problem is I need to order a cartrige feed control spring and the other problem is that it will eject every round out the chamber except the the very last one. So my question is, has anyone had this problem with the fte and secondly how can I identify what year this rifle was made? Thanks
