I didn't say the club sold it in the Eighties. I said that the owner acquired it during the Eighties according to you and that was a time when the club was in turmoil and very few people were interested in it.
To be honest, I doubt that most of this stuff actually was obtained from the club itself. Some of it was no doubt, but I've seen a lot of similar items to the 1927 stuff on eBay or up for auction before.
This is obviously from a private a collection and I think it's pretty obvious whose it is.
