Conn 8DRS compatible ring set

I have damaged the bell on my Conn 8DRS beyond repair. The damage is fortunately limited to bell only.
I would like to know what other makes are compatible to the Conn 8D ring set, any idea on prices, new or second hand.
Very few instrument repairers here in Australia, one notable repairer has on his webpage that he is not taking on any new work.
Would anyone out there in repair land be willing to post me a suitable bell-- NEW or 2nd hand to suit this horn,
I just wish this had happened before I went to Memphis IHS45 as I could have taken the horn with me for repair or purchased a bell & brought it home with me !!!!!
