Brown Square Gutter short length & any bits (Hayling Island PO11)

Am visiting a friend next week who has some failing gutter. Last time I visited I fixed most of it but was short of a length of gutter and a join. Couldn't get any brown and had to use some black bits. Anyway if anyone has a 1metere length Or even 1ft, of brown (or black) square style (floplast) guttering and any bits it would be appreciated and I can complete the job. Many thanks.
