Another martini rimless extractor

I bought this martini in .222 from the Australian Antique Arms Auction in May.  I thought it would be a .222R, but found it would not chamber a .222R cartridge.  Upon disassembly, I found it was meant for .222 Remington cartridges.  I don't seem to be able to post multiple pics tonite, so please bear with me...

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.

Here is a side view of the extractor.  You can see that the extractor had a slot milled to accept the pinning mechanism of the arms.

It works pretty well.

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...

BP:  Good call.  Doesn't the side lever put the torque on the extractor, rather than the breech block?  It looks that way to me.  What the heck, I'm an electrician, not an engineer.

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.

Harry

Bob Snapp of Snapps Gun Shop made a similar extractor for years.     ...MIKE...

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.

        I remember seeing your rifle at the auction It is a very nice looking Martini and I think you got a great rifle for the price but I though it was in 22 Hornet.
