Teague springs immediately to my mind

Definitely Teague.

I had Brileys in my old MK38 and they patterned really well, got my K80, had it Teague and it patterns superbly. Both really good but now I’ve had teagues I would opt for them every time, service was great and when I phoned up to order some more they were there in less than a week.

If buying new I would order one with the chokes I wanted. If SH I'd use Teague. Also, there are some around new fitted with a Teague multi choke conversion.
