Astra 44 mag

Question
I picked up an Astra 44 mag. some time ago (approx. 15 yrs.) and know nothing about it, in terms of approx. age and value.  I seems to be a good shooting gun.  I can find no info. on it anywhere.  Anything you may be able to provide would be helpful.

Thank You

Answer
I am assuming it is a revolver based on caliber. Astra made them in .41, .44 and .45LC from 1980-1987, in 60% condition it is worth about $160., in 100% about $280., add $100. if it is stainless. Astra was in business from 1908 until foreclosure in 1998. Thanks.
