From what I could find out this .44 cal. revolver was produced by German immigrants during the CW in the little village Sisterdale in the Texas Hill Country north of San Antonio.
Only one specimen seems to be existing.
My "crazy" Austrian smith would like to rebuild one for his collection ... like he did a the Colt 1855 Root Dragoon a few years back.
I would like to get in touch with the current owner to find out some of the technicals specs for him.
If you can help with information regarding the whereabouts of this one revolver please, let me know by PM in confidence.
Thanks & regards,
Long Johns Wolf
