G'day @Cavalcante, there is another possibility for you to consider. But first, have you a particular attachment to HMS Abelia? If so, then I understand you wanting any model of her you build to be accurate. A number I ships that I've modelled have appealed to me for a specific reason and hence I've gone to a bit of trouble in researching them for an accurate model. And most of these have been ships with only a few sister-ships.
But many of the escort vessels, Flower class included were built in large numbers. And as @robgizlu has said above (and you've probably gathered for yourself anyway) there were a lot of variations in the Flower class corvettes. Many of them would have served in often appalling conditions with their crews enduring considerable hardship, all helping to win the war, with many never being given the opportunity to take part in a specific action that made it into the lime-light and the history books - they simply slogged it out unrecognized for as long as they were needed.
The point I'm trying to make is this - If you don't have a particular attachment to HMS Abelia (or any other specific Flower class) why not make a generic ship of the class, either short- or long- foc'sle type? This will save you a lot of research into a particular vessel, and possibly some disappointment if you find later that you've made a mistake, such as wrong camo patterns, slightly different equipment fittings etc. The hulls and superstructures will be similar if not identical between ships, and any model you make will be immediately identifiable as a Flower class. I did this when I scratch-built a Flower class corvette in 1/600 scale about a year ago. There were no kits available in my preferred scale that I was aware of, hence the scratch build. Admittedly my model is rather basic but I enjoyed building all the same, and I've labelled her a long-focsle Flower class corvette. Something for you to consider. HTH.
Regards, Jeff.
