I'd suggest either relegating it to the display rack, or maybe parting useable parts out on Ebay.
It was a cheaper gun, and has no collector value.
The 490 does not have the same barrel mounting system, and will not loosen up after alot of shooting. The winchester .22's are all nice guns. My son has a 290, a 250, and a 490, and they all just purr like a kitten.
