Hello all. New to the forum from sunny SW Florida. I recently inherited a Stevens Walnut Hill .22LR target rifle. I think it is a Model 417-2 with Lyman rear tang and 17A front sights. Front has sunshade. Marked 555 assembly / serial number!?!

The bore is nice and bright and everything appears in good order. No scope with it. It was my great Uncle's but it does not hold any sentimental value. He was a great guy and had left other firearms to me which I will keep. This one I have never seen nor want to keep. Any insights on it would be welcome. Many thanks.
