Thankyou for remembering us,it is sad and upsetting .
You sometimes see articles ,obviously from a Church at flea markets and antique fairs.
In the inner city areas in Manchester so many churches were demolished,new built all modernistic ones replaced about only five percent.
So much that would have been memorials just seen as rubbish.
The wholesale demolition of working class areas meant the congregations left before demolition of the local churches,so no one realised until it was far too late to rescue anything and what would they have done with it in a small cramped Council flat on the umpteenth floor if a tower block.
The diocese is at fault ,they had all the info,dates etc and could have published that these things were up for grabs and whilst the relevant documents were in existence.
No solution for your enquiries but you tried,really tried, and that counts.
Thankyou again.
Viktoria.
