I can certainly recommend Airgun World as my favourite airgun magazine. However, as regards a strip down article on the TX, I'm not in the know as to when this may have been presented.
However, great news......The TX is, very possibly, THE easiest rifle to work on, period. There are lots of text and video tutorials on-line. Have a look at a few to get a general idea. And be sure to shout up on here for any further advice / queries.
