Hmm, if only there were a "search" function in PPRUNE. Oh yes, I remember, there
is. 
VFR Transit: much detail in
the previous PPRUNE thread on Air Wales. I think the last post there may answer the question about what an ex-Air Wales aircraft was doing at STN, but if not, I suggest you ask in the Spotters Corner forum.
Thanks for the gratuitous A.net hyperlink, though. You know, I'd
always wondered what ATR42s looked like...
