I think that is what makes some of the imports look "odd" after looking at pics of the originals, the rear lock bolt center and tang bolt center are good references for pulling lines of radius for comb lines, mouldings, buttplate facets on the heel extention and a variety of detail...on most originals
I wholeheartedly agree. The human eye is amazing at centering and aligning (that's why peep sights work so well and we can shoot sightless bows accurately). To my eye, the forward end of the patchbox HAS to point into the center of the narrowest part of the wrist or it just throws the whole rifle off. In Liver eater's photo above he's got it right. The buttplate end is less critical. His has to be a bit high because of the grease hole, but it still works. The original smiths were brilliant at pulling lines together. Something as simple as a straight toe mortice along the bottom edge of the buttstock can make a rifle 'look' much slimmer and more streamlined.
Here's an example of a miss (God, I hope no-one on this list made this piece)
The box points at the front screw of the triggerguard and it just doesn't 'flow' gracefully like a classic.
A Traditions - patchbox pointing up at ???? Comb has nothing to do with the toe lines. Very awkward to my eye.
Pedersoli - not bad. Showing that there is no reason a production gun can't have good lines.
An Allen Martin Lehigh copy - now tell me your socks aren't rolling up and down after seeing this in a line-up with the above.
A recent copy of a Moll (by Eric Kettenburg): Allentown School
A Rupp copy (also Kettenburg): Lehigh School
Subtle differences - check out where the hump is on the underside of the wrist/buttstock. Moll blended it in to the triggerguard architecture. Rupp lets it sit out on it's own. Not many of you were probably concious of the difference at first look, but one stock may have appealed to you more, even though they are very similar designs.
It all comes down to personal tastes, I guess. (And, perhaps you can tell, I love the Lehigh & Allentown style of longrifles)
