Did someone take a tap and thread your takedown pin journal to accept a screw?

I think a view of the pin opposite (180 degrees) of the spring might help.

---

I just found out where I had 'swiped' that image of the pin. It was from a post to this 'site by member Deeangeo on July 27, 2015. Here's another from the same post:



The pin simply pushes into place and clicks shut. The notch in the sprung portion is pressed outward by spring tension to engage the thickness of the escutcheon plate. To remove, press the knurled part of the sprung lever with finger or thumb and pull out pin.

To 'take down'; remove magazine, turn lever in front of trigger guard, pull forend pin (as described above), lift barreled action up and out.

And it's stamped 62
Last two of serial number?
Is that a view of your rifle, Rothhammer?

The little round pin and the rest of the spring are no doubt all one piece of spring steel.

That should help xausa get his part made.

If this is indeed your rifle, and if you have a caliper and/or micrometer, can you verify some dimensions?

---

Those were Casper's images, I posted them via Picr.de .

I noticed the '62' in his image as well, and didn't recall ever noticing a number on the pin of my M1910.

Now I have mine in hand and there is no number. The knurling on my 'spring release' is also different, consisting of parallel lines rather than cross hatching. As far as I know it's original. The rifle was proofed in 1922 and Grand Dad acquired it about 1932 in Ceylon.

What dimensions do you require?

The dimensions on mine match those of the image above except that the 'Cap Dimension' of mine is .445", not .466" as the one pictured. Also, my 'spring height' is not as much. I don't know why the one pictured (with dimensions) is protruding so far.

I can't seem to get a decent scan of mine, and I'm not set up for 'macro' photography (though I should be). This at least does show the parallel lines on my spring release, rather than cross hatching as on the others. The 'Cap' on mine has the reeding as the others:

That appears to be the case. However, I have not removed it, for fear that it would not go back if held in place some other way.

You may well be right about fitting. Casper might be able to answer that question, since he bought an original one. Did it fit whatever rifle it was intended for, or did it require fitting? Louis reports that his replacement pin fit perfectly.

---

Here's how they fit (images from a Gunauction listing):





Notice how the fit of the pin and the escutcheon plates is rather precise. As replacement pins were available from Steyr, and we are dealing with Pre WW2 Mannlicher Schoenauer craftsmanship, I rather suspect they were all the same dimensions as to length, taper, 'notch'.

For yours, if those escutcheon plates have been buggered to accommodate a screw in place of the proper pin, It's likely you'll have to fabricate new plates with the proper sized holes.

If only it was 1939, a new 'Spring Pin' would cost one dollar from Stoeger (about $17.50 adjusted for inflation), the same as a sight protector. The spring for the pin was another $1.25, new cleaning rods were a whole $3.50:

I have a friend who may be able to duplicate the pin, using the dimensions so kindly posted by Rothhammer. However, I need someone to explain to me how the spring catch works and how it is fastened to the pin.

---

Hard to see, here, but #85 appears to be the pin without spring (notice 'slot' lengthwise, just below center) and #86 shows the shape of the 'spring'. Spring seems to be one piece machined spring steel that simply fits in the pin's hole and slot.

With the dimensions I requested here, we are very close to having all we need to make the part.

The spring in Mike's pin looks like it has some cracks forming near the little pin.
I wouldn't attempt to remove it unless I was planning on replacing it!
