Hi Tony
There are open days at the Blackpool Keyboard Festival on the Sunday and Wednesday, if you can pop up there you will be able to listen to and try all the items you mention.
The Wersi Theatre Organ samples are excellent sounding but they are not of the Wurlitzer type, but Barton and Morton type.
Also don’t forget there are plenty of Akai samples and VST instruments of Pipe Organs.
Wersi do have samples of the Blackpool Wurlitzer, but as of yet they have not been released.
TTT is not as good as it was due to the fact that a lot of the original samples of the Blackpool Tower have been removed. (Wersi have the rights to Blackpool Tower samples)
The Roland Theatre Organ sounds are sampled from an American Wurlitzer Pipe Organ, and sound superb.
Classical Pipes again vary between manufactures, and there are also plenty of Akai samples and VST instruments about.
