Issues with an A&A No.2

 Here's an AyA No.2 with a few problems.  The first of these are cracks at the stock horns, the second is a broken striker, the cause of which will be covered in that segment of the post and, finally, a faulty ejector mechanism, caused by half-assed "gunsmithing".  Let's dive right in...

The cracks at the head/horns that made their way to the rear of the lockplates...

The stock and forend were stripped and de-oiled in preparation for repairs and refinishing.  After repairing the cracks, the pull length was adjusted to the client's specification.  A new buttplate and screws were also made to match his other AyA's original black plastic buttplate.  The stock and forend were then refinished and the checkering recut.
With the wood finished, I turned my attention to the ejector mechanism.  As you can see in the photos, the right-side ejector tumbler had been welded, in an attempt to build up the trip surface. 
Beside being crudely done, the weld "repair" would have a very short lifespan (as is obvious from the below photo), so a new tumbler was made from 01.  After disassembly, I discovered that the dipshit had also welded on the right-side ejector mainspring, rendering it useless as well.  A new spring was made from 1095.

Upon inspection of the broken striker, I discovered that both pieces of it were bent.  Further inspection revealed that the bore of the striker bushing was not concentric with the striker bore in the frame.  This was undoubtedly the root cause of the failed striker.  It also made me wonder if the other striker assembly suffered the same malady.  It did.  The left striker, though not yet failed, was clearly bent, purposely, to accommodate the misalignment and eccentricity of the striker bores.  The hazard inherent in this situation cannot be overstated.  Imagine closing a live round on a striker that is stuck fast in the extended position.  This necessitated making not only both strikers, but their respective bushings as well.

The bushings were made first (of O1).  Their bores were made undersized and line-reamed in place, concentric to the bores in the frame, using a shop-made D-reamer.  The new bushings are then finished flush with the breechface and drilled for the vent screws (which retain the bushing).  After making the new strikers (also O1) and verifying their freedom of movement, the parts are heat treated and finished.  New springs are made and installed as well.
