Any of the old 'Wilkinson Sword' ones sharpen up well. Modern-ish (I've been using mine for over twenty years now and they are still excellent) that say Fiskars, and not made in China, are worth trueing up.
Honestly BR, in competent hands, so long as the shears haven't been totally abused, the middling aged ones all are sound when renovated.
J. Rodger's and sons are good, and I have Wright's too, (they used to be marked Kutrite) and they are excellent, so are the older (not black handled) Singer ones, and they came in different sizes.
J. Nowill & Sons are another reputable company.
I can have a trawl through ebay for vintage ones that I'd buy if that's of any help ? Tom will probably have a fair idea of good ones to recommend too though
