I purchased this rifle a few years ago at auction. I don't know much about these muzzle loading rifles.
It is marked Dobias & Howsky (or perhaps Dobiaschowsky) in Perchtoldsdorf. I understand that Perchtoldsdorf is in Austria.
The rifle is in very good condition (and appears shootable). I did not weigh the rifle but it is very light and compact with an overall length of 39 in., a barrel approx. 23in. with 3/8 in. width of barrel flat, LOP is 13.5 In., Bore is approx. .50 in.
It has a beautifully made folding peep sight on the wrist. This sight is in excellent condition and smoothly adjusts for windage and elevation. It also has an open sight on the octagonal barrel with one standing and one folding leaf. It has a horn muzzle cap on the fullstock, double set triggers, and very extensive checkering and engraving.
Any information that you can provide about this rifle will be very appreciated. Thank you.
