I agree Dave (SD). The butt plate has a lion; the trigger guard, a tiger; the breech plug a wart hog; and the lock plate a stag of some kind. I have had no opportunity to check for a tang sight support under the wrist escutcheon, but that is a possibility. Those two screws seem overkill to attach a simple escutcheon plate.
I used the new posting feature, and it was indeed easy to use. But am I able to access those images outside of the ALR thread?
