There are plenty of websites for guns. Ethnographic guns could be construed to mean guns used by the British empire during the Victorian era. Certainly in line with a study of swordsof the Moro's in late 19th and early 20th Century which is done here. But would Victorian Guns or European swords of the 19th and 20th Century for that matter be in keeping with the spirit of this forum?
This board seems more focused on the artsy decorative ethnographic arms than the standard run of the mill working arms. Although the standard arms aren't turned away and the those beautifly decorated weapons have ceratinly been put use. Your two pistols fit right in here.
There use to be a Balkan Arms forum, but I haven't seen in a couple of years. I thought it was
www.vicmart.com but looks like I am wrong.
By the way a nice set of pistols and they would be a most welcomed "decoration" in my house.
