Glad to hear that though unnumbered the Brute is likely an early copy due to a small run MONSTERLUVER.
That’s cool …doesn’t bother me, I just thought all the Sig masks were #'d thats all !! No big deal…it’s still Awesome regardless !! 
I thought it was cool also, that it doesn’t have the mask slit up the back of it !!!
My Sandman, possibly the prototype or #1 copy. I re-did the eyecuts and paint (the flesh looks brighter/more orange than it is) and added the lip bump.
My Shanks #2 (on your left).
Just sold my Brute. Also have a GPW (#26 I think, I’d rather have one earlier in the run though).
