Here is a head-on shot of the extractor.  Please note that both of the extractor arms are jointed.  There is also a spring mechanism which keeps them centered.

EdBu,

Thanks for posting the pics of the rimless extractor. It appears to have been pretty well thought out.

I don't want to hijack your thread, but I also noticed that your extractor appears to have much more material present on the extractor actuating "arm" that the block contacts during extraction than appears to be present on the extractor seen in the side lever martini post. Just thinking maybe...

EdBu,

That is probably the most ingenious solution to the problem of extracting a rimless case from a single shot rifle that I have ever seen.

I think that the whole extractor has been made by the gunsmith, rather than altering an original, as there's a rather poor fit between the arched cut out on the lower front of the extractor where it fits over the arched extractor pin housing. Compare that with the far better fit of the same cut on the under lever.

The twin hinged extractor arms do look to be a far better engineering solution than the method proposed and used by by the late Frank DeHaas for a rimless extractor.

I take it that there is a transverse hole between the two extractor arms beneath the hinge pins in which there is a coil spring that exerts an outward pressure on the arms thus pushing the tips of the extractor into the extractor groove in the cartridge?

That's how it looks to me.

The snap extractor I have a drawing fore somewhere is a springloaded blade that comes up into the bottom of the rim.Had a friend with a Martini in 223 set up by Snaps. Probably one of the better Martini smiths in the country. He is usualy buisy and takes his time.
