Hi I am new to the forum I have several single shot rifles. My latest find is a Swiss Martini in 6.5x55mm rimless This is a basket case most of the parts are there except for the wood and a few screws I would like to find somebody that has one.

CAP'N:
     Strange caliber for a Swiss rifle.  Sure it's not 7.5x55, or 7.5x53.5?
I got one recently, just to see how the extractor worked for a rimless ctg in a Martini action.

Chri6,This is what the previous owner sent me. "It has a 35mm land diameter, 6.50mm groove diameter and the Norwegian/Swedish 6.5x55mm cases are a perfect fit in the chamber which has an extractor for rimless rounds.
I know very little about the Swiss Martini. I actually got it for the action but I may keep it the way it is. There is more pitting on the action than I thought but the barrel is great. The tumbler is broke and I need a picture of one to make a replacement. If you could help I would appreciate it.

JACK:
    The Swiss Martinis seem to be more alike, and not each different from the next, like the German ones are.  No guarantee that the part that you want to reproduce will be EXACTLY  like mine, but in a few days, I will send you an image of it, to look at.

Hammerli made big Martini free rifles in 6.5x55 back in the 1960s.  Maybe it is one of those.

Captjack,
As CHRIS said, the Swiss Martini's tend to have very similar internals. They frequently have DST, so the sear is separate from the trigger,unlike the British Martini's. They also tend to use a barrel dovetail for a sliding rear sight as opposed to the German Martini that uses the tang diopter sights.
I acquired a Swiss Martini that had the wood and breech block but was missing the internal parts. Below is a photo of the missing parts, that were made by studying an intact Swiss Martini and then trial and error. As also stated above, the parts require individual fitting and the precision required in fitting will give you a new appreciation for the skill of the old time gunsmiths.
A picture of your action and the parts that came with the rifle will give us an idea of what parts you need. Then photos or drawings of the missing parts should get you started.

Captjack,
It appears that you have most of the parts and are only missing the sear. There a variety of ways to make this part, depending on what you have available.
Below is a photo of the sear from a complete Swiss Martini, that I used to get a general idea of the shape.
You can determine the position of the parts using the holes in your frame to make a test plate.
Photo #2 shows the original parts in proper position and photo #3 shows one of many test sears that I made.
If I had to do it again, I'd make the test sears out of wood, until I had the proper geometry.
An easier approach if you have access to a Soldworks design program, is to model the parts that you have and insert the missing part into the model. You can then test function to be sure that there is no interference.
On the complete Martini, they used a leaf spring but on the incomplete Martini the leaf spring caught on the through bolt and a coil spring worked better.
It can be a little frustrating making the sear, so if you have additional questions, you can ask them here or email me.
Otto

Thanks for the pictures it will help I don't have that program available yes it would make it easer but I will have to do it the hard way. I will try to make them out of wood. I am better with wood than I am with metal.

Chipmaker's picture of Martini parts above is what really helped me make a new toggle for a German Schuetzen Martini that had an incorrect aluminum part in it when I first bought it.

Check my recent posts on that one, as I show how I used hard plastic (1/4" sheet material sold at boating supply stores) to make several iterations of parts -- quickly and easily -- before I found the dimensions I needed on 3 critical points.  The plastic cuts and trims very easily; then you can make an aluminum proof part to confirm dimensions before making a final part from steel.
