I would Grab that one!
I have never owned a WMC, But I do have a TC New Englander in .54 Cal, LOT of Similarities, Stock/Lock/Trigger Group
My complaints with my New Englander was the Single Non adjustable Trigger, The Pull was HORRIBLE at best. I ended up doing a Modification to the Tumbler/Hammer to lighten the Pull.
The other thing was the Odd “Beak” Shaped Tang piece that doesnt allow you to Remove the Lock, Unless you Remove the Tang (Stupid Design??) And since i have a Tang Mounted Peep sight, Having to Remove the Tang in order to Remove the Lock just wasn’t an option that i was gonna live with, So Out came the Hacksaw for another Modification
I really like the Rifle now! Trigger pull in the 2-1/2 pound Range, and i can easily Remove the Lock WITHOUT removing the Tang
