Can anyone tell me what the differences between the Standard Mk. 3 and the Deluxe version are?

As far as I can tell the only difference is that the Deluxe has a Gary Caine Grade 3 stock and a Rosewood Pistol Grip Cap.

Is there anything else?

Is the Deluxe worth the extra money (approx. 150 pounds depending where from ofcourse)?

Who makes the standard thumbhole stock then?

Any information appreciated.

Thanks.
