The cabinet design is the same as what M&H marketed as the "Queen's Model" because it had been designed especially for and presented to the Queen around 1886. It had a very harmonium-like action inside, with 2 16ft ranks, and a keyboard division above middle c. But my organ has has a full-on Liszt Organ action installed instead, and has a different style number. The Q's model was Style 512, this is denoted as Style 513. If you are a regular reader, you know that the M&H Liszt Organ was named after Franz Liszt., and the great composer and keyboard master collaborated with the company in its design and specifications.
It remains the only one of its kind to surface. I think it has a really great sound, and it is really powerful in person. It is very nice because the casework is so minimal, and it takes a little less room than other Liszt models.
