Need Information on Old Remington .22 Pump

[BarkeyVA]

Trying to find information on this Remington .22 pump rifle. Pedersen patent. Letters RW above the serial No. 181xx on the bottom of the frame. I think it might be a Model 12 C . I'd like to confirm that it is a Model 12C and when it might have been made. Also, what its value might be. Any information anyone can provide would be appreciated

Early model 12C with octagon barrel.
The tang sight adds value
Condition is everything and if the bore is good and the weapon not so worn that it still functions reliably, $500 at retail would not be too far from the mark. HTH

12As were in .22 Remington Special
12Bs were in .22 short caliber
12Cs .22 Long Rifle
