For once in my life I will keep my mouth shut about that, other than to say that I think all judging programs would benefit by having printed guidelines available to all participants, prior to entry that spell out judging criteria, terms and conditions, and judging values of different aspects. As things stand at present, entrants are shooting at moving targets.
Now, I promised to list identifying characteristics of Lehigh rifles. This list is neither necessary nor sufficient to identify all Lehighs, and period of manufacture makes a difference, but here are some things to consider:
Sheath buttplates common,
Two-piece, wide patch box with Fleur-de-lis finial and engraving,
Classic curvilinear buttstock profile with double radius at bottom (lost on later examples),
Spade trigger,
Trigger guard with wide bow and pronounced stud forward of the bow,
Wider than high wrist (lost on later examples),
Thimbles with 16 facets and a thumbnail in rear thimble (later examples sometimes lack a rear pipe),
Tiny sights,
If present, the nose cap should have an open front,
V-shaped contour to forestock.
If patchbox is present, release normally is at rear,
Occasionally the presence of the "Allentown Indian" and look for a prayer hole in the cavity if there is a patch box.
There are some constructive guides for you Lehigh builders.
