Spencer parts

[Fazer]

I was digging through one of the parts boxes looking for a screw. Came across a small bag in the bottom. Are these all Spencer parts, the extractor looks right. Not sure where they came from. Any help appreciated. Thanks

The four knife-blade-with-a-hole-in-one-end pieces are Spencer extractors. 
The four largest pieces with notch in them are Spencer firing pins. 
The four pieces with peg in one end and hole in the other are Spencer magazine detent springs. 
The four tombstones with holes in them are Spencer magazine catches. 
The two paisley-shaped pieces are stirrups and could be Spencers, although it depends on the size.
The two T-shaped pieces look familiar, but can't place them.
Also not sure about the four little "chips"

Hello, Fazer:
I agree with DJ.
I sent you a PM. Smiles.

Hello:
A parts expert indicated the "T-shaped" items are Trapdoor items.
I looked at Trapdoor parts and the four flat bits seem to be front sight blades.

The 4 chips are indeed Trapdoor Springfield front sight blades. The studs with the angled tops are cartridge case deflectors for Trapdoors. They rivet into the bottom of the receiver. When you open the breech, the ejector throws the empty case straight out the back of the barrel, which then hits the sloped surface of that stud and goes somersaulting out of the action. Original Trapdoor shotguns do not have that deflector, so the empties stay in the receiver for easier retrieval.
