Welcome to the Forum!
As Robb has pointed out,,, it's worth whatever you paid for it. Of course, Robb buys guns, then spends a lot of $$ chopping, modifying, & in general customizing them.
If you feel it was a fair deal, who cares what you paid. If you do an on-line search of a gun auction site like Gunbroker, looking at completed auctions, & find the same model as what you have, you will see what the market has said. But, also look at the dates of the completed auctions. A 3 year old auction sale price can be misleading.
If, by chance, you find you paid a bit too much, do not fret. If you like the gun,,, who cares? And a wise old gun trader once told me this; "You never pay too much,,, just occasionally too soon!"
I'm not help on your gun, as I focus most of my knowledge on pre-1973 Rugers. (Unless it's a gun I like & then I buy it!)
