Hi,
June'02 to June'04 would be 24 issues (excluding specials)?
I've looked through Nov'03, Dec'03, Jan'04, Feb'04 and Mar'04 and I didn't see any sign of your chrono related letter there. So only another 19 issues to check.
It was a interesting to re-read some of the articles of the time and salivate over the adverts.
