Maybe it is just me but I don't think appeals for money towards buying locos for preservation will bring the coffers in like they used to, for example if you decided you wanted to preserve a 37, set a group up and asked for money to help who would give to it? There are so many in preservation and there are guys who have the cash in their pocket to buy one (and in some cases 4,5, 6 engines) and restore them. If its an existing engine group owned and has had a major failure then you may get people giving but with the currnet amount of locos in preservation I can not see people dipping into their pockets and producing money for every group that turn up on the web thinking about buying an engine.
