Model 1890 question on barrel length|Winchester .22 Rim Fire|Forum|Winchester Collector

With a serial # in the 370,000 it was not a 22 LR when it left the factory. The 22 LR was not available until the 620,000 serial range (1919)  Is there a circle P stamp on the barrel?  (Not WP) That would indicate a non factory replacement barrel. Barrels other than 24″ were available special order. Seeing as the barrel does not match the receiver, chances are it’s a modified barrel.
