114mm square upvc guttering

[scottS3]

Hi, I'm after a length of squareflow type guttering and fascia brackets to match the existing stuff on the house. The only manufacturer ID I can find is on one of the 45 degree bends on the conservatory, which has a bold/italic H and made in england,patent pending.
Can anyone identify it from this? I thought maybe Hunters plastics but they have a different logo?

Any help would be great.
