Hello ChiefShotguns,

In addition to what Mr. J.D.Steele has said, if you look at the photograph of the Neidner modified Borchardt, built for Dr. Baker (above) you will see only two large pins near the front of the action. One is the lever Pin and the other a take down pin which when drifted out permits the barrel to be unscrewed as J.D. said

In this particular rifle the Cam Plates are not necessary as the action is hand cocked before firing, therefore the cam plates and their locating and screw holes (three holes each side) are not required and in this rifle were either welded or rivitted to close them. The breechblock is a new and highly modified version of the Borchardt breechblock, the original being discarded.

To avoid the firing pin digging in when the action is opened I believe there is a small notch in the cocking piece that permits the firing pin to be locked back just enough to enable free opening of the breechblock. The small pins towards the rear are as described in J.D's.post.

Michael Petrov should be applauded for his willingness to show us such a rare Borchardt.

Harry

Another Zischang, this one in caliber .28-30 which belongs to a friend here in town.

Notice that most Zischangs have the cam plate pin (in the center) replaced by a screw. Hard to see in these small pictures frown

why the screws and not pins? I recall there was a reason but I can't remember what it was.

Hello Michael,

Many thanks for the pictures of the Zischang safety, it's had me scratching my head for some time. Now I've seen the drawings, I'm even more puzzled. I'll have to have a think about this one. A two pipe problem Watson.

This may be just a shot in the dark, but the centre pin locating the cam plates goes into a hole that allows precise location of the cam plates, but, if replaced by a screw then these plates have a little leeway in movement which would allow a tiny bit of juggling about of the cam plates. Perhaps it was an easy way of getting the two cam plates into precise adjustment.
Just a thought.

Harry

Once again, If you log in and then hit "post a reply", scroll down and you will get a larger picture. Also, great stuff to view!! I want a set of Zischang trigers so bad for mine. O well! Has anybody seen a picture of John King's double sets?? He told me that he has several sets out there on trial basis. They're based on wsds that Winchester used on their walls. Bob

The flat side of the Borchardt also makes a nice canvas for the engraver.
