354th Fighter Squadron (WR) / 355 th FG
Just from my experience on the 55th FG Skinpack and research, it's best to go for research/search querries on the Fighter Group, even if you're just after
one of their Squadrons. Usually the sources are collated under the whole Group, with Veterans Associations Pages split into sub pages of the Squadrons.
Check the Wiki Page for 355th FG, for Veterans Pages, Association Sites, Publications
Some Association Sites you can still access through Web Archived Links even when long gone, I had luck at the 55th FG
2 publications on the 355th FG and WW2 in the Bibliography section listed, Steeple Morton Strafers for +100$ Woohoo, the other sells for 13€
(The pain of passion, it's cheap, really, some WW2-Aviation topic Books sell for +500, me and my Me262 freakdom or RLM-Paints related publications)

If you're already fed up, scratch it.
