single shot rifle in 10,5x74R (? maybe a typo and its a 10,5x47R ) with octagonal barrel
serial number 302 what dont fit into my theory that all hunting guns are in one serial number range
it have crown + "V" proof what puts it into the early 1890s. I think it was made in this years when Dreyse was in decline and they use everything laying around.

it looks like the action of a Baden customs needle fire rifle made after the war of 1870/71 and still in use up to 1900 when it was replaced by Haenel made M 88 carbines

possible Dreyse was using old parts for this hunting rifle, rare and interesting single shot I wish to have it

no, think I have find it
here is a similar experimental dreyse rifle in 11,2x60R
smooth barrel with roatationskammer made in 1874/75 when first problems with the Mauser 71 occur

so the hunting rifle above may be build with a receiver left over from this trials but its clear the Baden customs rifle was the starting point
