Remington model 870 Wingmaster Mag 26" VT 20Ga Rem Choke

[dhenzler]

Have been after a Wingmaster 20ga 26" Vent Rib with Rem Choke. This is the best I could find. Serial CC6875?? Order 26949. Box label says made in Illion NY. The barrel is also marked Illion NY. The barrel marking is very small.

There is no lock on the trigger group. Barrel markings are roll marked, not laser. How can I be sure this wasn't built from leftover parts by Rem-Arms (Ugh).
Curious what you think
