Hello... I was wondering... does anyone have information regarding the rarity of the different states of the first UK edition of Letters of J.R.R. Tolkien (1981)? The three states are listed in Hammond pp. 350-351 and I'm curious as to how many of each are out there. My copy seems to be the 2nd state. Does anyone have the first state or either of the two variants of the third state?

Thanks!
