1944 Trials Lee Enfield No 4 Mk 1T .303 Sniper - Bolt Action Rifles at GunBroker.com : 834741376

I'm tempted to bid on it but the lack of a T stamp on the receiver has me concerned.
I have one of Roger Paine's mounts & would gladly buy a refurbished No32 scope to complete this but I just don't know.

I recently picked up this, I know it's not the right caliber but it certainly has the look, with the exception of the mag that is
ENFIELD, 303, CUSTOM -L42A1type - Bolt Action Rifles at GunBroker.com : 835291655

I really want a L42A1 but I have never even seen one for sale. Do they ever come up for sale?
And what do they go for?
Thanks, Mick
