Hello. I had several of these gutter brackets break in the recent snow but I'm having great difficulty in sourcing replacements. They are from a conservatory but I'm afraid I don't know the make. The small tongue shown in the green circle has broken off in the red circle. The only identifying mark is "RS32790". It is a “twist in” internal (ie it sits in the gutter rather than underneath) bracket but does not appear to be Ultraframe, Global or K2. Any help with identification or more importantly, a supplier please? I will need about half a dozen.
