The first one is definitely a Number 1 Mark VI.
The second rifle is definitely a Trials Number 4. Likely it will be marked on the butt-socket, same as an SMLE, and it will say
GR
ENFIELD
1931
No4Mk1
I would give my eye-teeth for either one of these (if I still had teeth, that is). I MISSED a Trials Number 4 at the Brandon Gun Show a few years ago and I'm STILL crying over it. Thing went for $350, too, just to add insult to injury..... and it was in BEAUTIFUL condition.
Many of the Trials rifles ended up being converted to (T) status early in the War, which just makes the few that survived even scarcer.
From a collector's standpoint, either of these is extremely important. Together, on the same rack, it would be pretty darned hard to beat.
