COLLAR for Gas combi boiler (Harrogate HG1)

I gave this boiler to a freecycler 3 months ago sorry i cant trace the name. . I have found the missing COLLAR for it !! If you can let me know when you would like to collect , i will leave out for you . There is also wall bracket and a flu bend ! .
This boiler came out of an annex to the house next to us . It shared the gas supply.when property was split. They had to consider putting in a new supply line. The gas wanted £3000 to do this. So this boiler was taken out only after a year in service .it was working when it was taken out .
