a double gun in "18mm" probably 074" sold by Hermann Historica in 2008
with the upper cartridge ectractor hooks but the old style lock release lever

the underlever is cased with horn something rare but also in combination with a lower grade steel made gun here if we think that the damascus steel made guns were allways higher grades and more expensive.

as a "16mm" this is probably a 070"
beautyful damascus steel and the inlay work in gold and not in the common silver, the serial number 8871 also in gold

sold by HH in 2009

a "17,5mm" ? maybe a 0,74" serial number 3815

sold by HH in 2009
