Serial number of my Montefeltro is 10838, 20 gauge model 20E. Can someone tell when it was made?

So far I shot 50-60 rounds with no problem.

I bought it used. I do not know when it was made. I can tell it was used intensively for many years. Blueing on the barrel is quite worn. Yesterday the gunsmith replaced the whole bolt assembly with a used one and also replaced the recoil spring with a new one. Then I went out hunting and shot 5-6 rounds with no problem. I will try more shots on my next hunting trip.

The extractor hook may worn or extractor spring may be weak. So the bolt assembly cannot pull the empty shell out from the chamber.

A local gunsmith here in Korea thinks the extractor spring may be weak causing incomplete extraction of empty shells from the chamber. I will have him replace the spring and report the result to this forum.

When fired, the empty shell does not eject from the chamber at all. Or it does not fully eject as in the photo. If I disassemble the gun and thoroughly clean including trigger assembly and oil it, it becomes good for the next a few dozen round but the problem starts back. I always use 3 inch shells only. Any parts need be replaced?
