I could use some help from those of you with experience in the
identification of gun part manufacturers.  Of numerous arms and
munitions related artifacts from the Russian-American settlement at
Castle Hill (Sitka, Alaska), markings are present only on a single
sideplate.  The context is believed to be early 19th century.  I've
posted a photo and notes at http://home.gci.net/~sncnuka/Daves-Photos/.

Thanks,
