So, the link I was using on Flickr was    https://forum.keypublishing.com/showthread.php?145051-AVRO-hangars-for-…

And the new link is                                    https://www.key.aero/forum/historic-aviation/148567-avro-hangars-for-sale?page=0

I have tried substituting the large number in the new link but that comes up “not found”. However, changing “page=0” to “page=3” takes me to the page where my contribution starts. Mind you could have seen that by just looking at the URL for page 3.
