Gull guard cage for chimney (Westham, Weymouth DT4)

Gull guard cage for chimney, from Weymouth.
Prevents gulls nesting on your chimney pots or flaunching.
Width & depth both 97 - 98 cm square (98 cm external measurement)
by height 122 (internal) to 125 cm (external measurement ) to highest point
Height from bottom to where the sloping triangle begins is 76.5 cm high (internal) 78 cm (external measurement)
You screw it into the stack. It is for a stack with 4 tall chimney pots. It was made to measure; see photo of it in situ before it was removed. Count the bricks to tell if your stack is similar size. Many are!
It was supplied and fitted by a specialist firm new in Oct 2020; still excellent condition.
I no longer need it as I’ve had chimney removed.
(For safety, I’d recommend you use scaffolding and 2 of you to fit it to your chimney, but it’s technically not hard to fit.)
Please email me, or tel or text my mobile - which does not take voicemail.
Thanks.
