Hi Freddy......welcome to TFF.
Your Husqvarna was made by Husqvarna, in Husqvarna, Sweden. They'd been making high quality firearms for almost 75 years, and then got out of the firearms busines in the late '70's/
I can't give you an exact figure on the value of your rifle without knowing which model it is, but depending on the model:
Exc. - $400 to $675
V.G. - $300 to $550
Good - $275 to $475
Looks like you got a bargain.
On your "1919" Winchester SxS.....I'm a bit confused here.
From 1879 to 1884, Winchester imported shotguns from England, but they were only available in 10 or 12 guage.
The next Winchester SxS listed is the Model 21, which was sold from 1931 to 1988, from 12 ga. thru .410. It was made in so many models and grades, it would be impossible to list them all here.
If you can give a complete description of your shotgun.....including all of the writing on it, barrel length, any engraving, etc., I'll try to give you a ballpark estimate of it's value
