Rat: you have mentioned a feature that a lot of contemporary builders overlook. As the castings come, they are simply canvases that require attention in the form of filing and polishing, to make them resemble the work of the past. Here's a series of photos that shows this work, for better clarity.
The same attention is required, in my opinion, to the hammer, as most Hawken offerings have a hammer than is grossly overweight. Reshaping the hammer to more closely resemble originals, makes aligning with the nipple much easier. In the case of the precarve illustrated here, it appears to me that the hammer has too short a throw, compared to the other two photos of correctly aligning hammers/nipples. And since the lock inlet is already done, nothing can be done to make it better in this case, apart from re-forging it.
