Is that a pin that I see there? If so, you should be able to push it out and the spring and ejector should come out. Cover the ejector so parts don't go a flyin'.

Here's a schematic for a Winchester Model 37 from Numrich. It shows an extractor spring, but it's sold out.

its the pin that is slightly recessed in the picture that holds the extractor/ejector in place. Is the chamber in the barrel nice and smooth when you run your finger around it? Maybe you just need to really clean the chamber. It should be smooth and shiny just like the bore. Remove the ejector and spring(careful it is under tension) and clean that area. try the ejector without the spring and make sure it moves freely with no binding.

This is pretty simple, just don't let that spring sproing away from you.

for the part try Jack First 1-605-343-9544 as to the removal these guys are right on. be sure to tell them what gauge it is as some of the winny parts are gauge specific on the 37-A

I have seen a couple of versions of the 37 As two,the Redletter and the Steel built are about the same, The newest version of the 37 must be post 64 with a rolled scrolled design on the side and looks quite a bit on the cheap side like their semi auto 22 Model 190s during that time. I have a couple of Steel built 37As made in the late 50s. One in 20 Guage and the other 12ga. The extractors are so sturdy, I can't picture anything that could go wrong. Both of mine had good care, and are like new. I could see a dirty or rusted chamber causing the fired shell to stick and maybe the extractor pull off the rim of the shell casing, or a dirty extractor not releasing the snap to pop the shell casing. However the fact the high brass is worst, leads me to think back to chamber vs extraction. Difficult to tell without an examination. Good sturdy little guns for the most part
