I bought the Flues 20 ga. for the princely sum of $125.00. The stamp on the water table was S 20, not F 20, however there is an F stamped on the forend iron. All serial nos. match. The gun is solid but has a small shallow dent in left bbl. Receiver is clean but has almost no case color. Bbl. blue is about 70% and spotty. Buttstock has been replaced with a piece of walnut that nicely matches the forend in grain and color, but it has the unbelievably common (for amateur stockers) too sharp nose at comb and a semi-pistol grip that is too bulbous and fat. Nicely inletted and well fit to receiver and original buttplate. I compared the stock closely to an original Flues and thankfully there is too much wood in a few places, but no shortages anywhere, so a little re-profiling can give it original dimensions. I'm still wondering if the water table stamp of F 20 and S 20 are both field grade guns.
