Regarding the Flower class book...if it's the same publication it's titled "TO SEA IN HASTE" (Acropolis Books 1975) written by Roland T Carr, an officer stationed on the ship. The book is pretty much unknown and only made one printing(as part of a bi-centennial series from the publisher). It's hard cover, 260 pages, and contains 20 B&W photos. The story centers around the USS HASTE, a Coast Guard manned, (modified) Flower Class corvette. It's a well written tale giving the reader a day to day look at life aboard these little escorts, largely ignored by American naval historians. Being a Coast Guard vessel, this may account for it's lack of interest by maritime readers who tend to favor the exploits of bigger naval operating units. Still, if you build Flower class corvettes, this book might be worth a read, every convoy didn't equate into a U-boat battle, rough weather and monotony were an enemy unto themselves.
As to building a 1:72 Corvette, I have you all beat. I purchased mine in 1979 under the Matchbox label. It sits 75% compleat in my "Shipyard", it took me a looooong time to decide in what configuation to build it. I have about 20 magazine articles dating back to the early 80's dealing with building the 1:72 corvette but everyone pretty much builds it out of the box. I wanted mine to be a little different and radio controlled. In the interim, I've built 15 R/C boats(mostly scratchbuilt) and the corvette model, which looked so "big" and sea worthy in 1979 looks pretty undersized these days. So I took the motor and all the R/C gear off and decided it will be a "shelf queen" when complete. The ship will be the USS INTENSITY configured with American weapons and deck hardware. Like others have commented, the GLS fittings are a little pricey but well worth it. I plan to purchase a set when I "save" enough money, being retired everthing is "cash on the barrelhead" these days.
Still it's an impressive model when completed,(there are some outstanding corvette models on the internet) all it takes is a little money and a little "time".
PS Snyder and Short have a great line of ACCURATE naval paint, US, British, etc. that are spot on, check out their web site, perhaps you'll find what you need..
