The Uberti lock is a copy of the Ithaca Hawken lock which is the same as the Cherry Corners Hawken lock.
Here's how similar the locks are. In this picture of a Uberti lock from a factory finished rifle on the left, a Cherry Corners lock in the middle, and a lock from a Uberti kit on the right, the arrows are pointing to the seam between the lock plate and bolster plate. Where the Cherry Corners lock was riveted, the Uberti bolster appears to be spot welded.
This next photo shows the internals of the three locks for comparison. Uberti factory finished top, Cherry Corners middle, and Uberti kit bottom.
The resemblance between the Uberti lock internals””tumbler, bridle, and sear””and the Cherry Corners lock internals are pretty obvious.
The hammers are very similar, also.
It seems pretty convincing that Uberti copied their lock from a Cherry Corners lock, either from a custom rifle or an Ithaca Hawken.
Note the spot welds on the lock from the Uberti kit. The indentions from the spot welds on lock from the finished Uberti rifle (top) are not as deep and aren’t as noticeable because of the color case hardening.
Now, Ithaca locks and Cherry Corners lock are about as hard to come by as Uberti Hawken locks, but knowing they are almost the same does improve the odds of finding one. I have found them on eBay in the past.
