I discovered this sample set by Melotone Sound Productions by chance and I just tested it.
https://sites.google.com/view/melotone-sound-productions/home/providencemethodist-conacher?pli=1It is 24 stops organ, extended to 37. The sample set was made from raw samples originally intended for another software. It is 16 bit and almost dry. It is typically an English parish organ as many were built in the early 20th century.
Very low memory requirement (1.6 Go) This sample set can be used with HW4 Free: one of the very rare 3-manual instruments in this case. It can be obtained on request via a form on the site. It is shareware.
