Just tried that and yes this causes a buzz, not really loud. The capacitor from the centre tap seems to be 15000pf measured out of circuit 16.4nF seems close enough. Going to have a look at the schematic now as we have determined the model. As its hard to read the print on the old black caps, I presume I can replace these with 400v film caps

First thing I did was cleaned the switch contacts, they are spotless

I can't imagine very many people had VHF reception in 1958 in Ireland.

Thanks again Mike for finding this, I now have the schematic's downloaded, its a great help, I googled for ages looking at images but could not find it.
